Oral The acute oral toxicity of the test material was investigated in a study which was conducted under GLP conditions and in accordance with the standardised guidelines OECD 420 and EU Method B.1 bis. Under the conditions of the study the acute oral median lethal dose (LD50) of the test material in the female Wistar rat was determined to be greater than 2000 mg/kg bw. Inhalation In accordance with Column 2 of REACH Annex VIII, information requirement 8.5.3, acute toxicity testing by the inhalation route is not appropriate, taking into account the very low level of particles of an inhalable size, based on results of particle size distribution study which indicated , 3.3 % w/w of particles are less than 100 microns diameter. Dermal The acute dermal toxicity of SiMn slag was investigated in a study which was conducted in accordance with the standardised guideline EU Method B.3. Under the conditions of the study the acute dermal median lethal dose (LD50) of the test material in male and female rats ...
The LD50 is usually expressed as the mass of substance administered per unit mass of test subject, typically as milligrams of substance per kilogram of body mass, sometimes also stated as nanograms (suitable for botulinum), micrograms, or grams (suitable for paracetamol) per kilogram. Stating it this way allows the relative toxicity of different substances to be compared, and normalizes for the variation in the size of the animals exposed (although toxicity does not always scale simply with body mass). For substances in the environment, such as poisonous vapors or substances in water that are toxic to fish, the concentration in the environment (per cubic metre or per litre) is used, giving a value of LC50. But in this case, the exposure time is important (see below). The choice of 50% lethality as a benchmark avoids the potential for ambiguity of making measurements in the extremes and reduces the amount of testing required. However, this also means that LD50 is not the lethal dose for all ...

The acute oral toxicity (LD50) of sec-alkane sulfonate-sodium salts SAS in rats and mice are reflecting the different grades tested in a concentration dependent manner. The acute median lethal dose of technical grade sec-alkane sulfonate SAS at 93% is between 500 and 2000 mg/kg body weight whereas sec-alkane sulfonate-sodium salts SAS tested at lower concentrations (e.g. 60%, 30%) revealed LD50 values above 2000 mg/kg body weight. Based on all available studies no indications of special target organs and/or specific toxic effects were revealed. Regarding acute systemic dermal toxicity, all available data do not indicate any toxic potential of concern. Data on inhalation toxicity do not exist. However, due to the chemical nature and physical form of sec-alkane sulfonate-sodium salts SAS inhalation is no exposure route of concern. ...
Oral The test material was investigated in a key study designed to be compatible with OECD Guideline for Testing of Chemicals No 420 Acute Oral Toxicity - Fixed Dose Method (2001) and Method B.1 bis Acute Toxicity (Oral) of Commission Regulation (EC) No 440/2008. Following a sighting test at a dose level of 2000 mg/kg, an additional four fasted female animals were given a single oral dose of the test item, as a solution in arachis oil BP, at a dose level of 2000 mg/kg body weight. Clinical signs and body weight development were monitored during the study. All animals were subjected to gross necropsy. There were no deaths, no signs of systemic toxicity, all animals showed expected gains in body weight and no abnormalities were noted at necropsy. The acute oral median lethal dose (LD50) of the test item in the female Wistar strain rat was considered to be greater than 2000 mg/kg body weight. Inhalation According to REACH Annex VIII, Section 8.5, Column 2, information on acute toxicity shall be ...
In toxicology, the lethal dose (LD) is an indication of the lethal toxicity of a given substance or The median lethal dose, LD50 (abbreviation for
The most widely used quantitative estimation of radiation sensitivity of a population of experimental animals is the median lethal dose or LD50. For reasons discussed earlier, a 30-day observation period is the standard interval used in tabulating mortality and the dose necessary to kill 50 per cent of the animals within this period is called the LD50:30. In practice, the LD50 is an interpolated value based on the response of subsamples to graded doses of radiation. Justification for this methodology is based on the following. If it were possible to measure precisely the minimum dose necessary to kill each individual mouse, a plot of the frequency with which each dose is lethal would result in a normal curve as shown in Figure 22-2A. Note that in this figure the dose scale is shown in terms of standard deviations from the mean minimal lethal dose for the population. Thus if the mean is 700 R and the standard deviation is 50 R the dose points corresponding to -3, -2, -1, ..., +3 are 550, 600, ...
The plant Nicandra physaloides (L) Gaertn, commonly known as the apple of Peru is a member of the solaneceae family. It has been widely associated with livestock poisoning in Kenya and elsewhere. The clinical signs reportedly associated with its poisoning are circling, tremors of the hind limbs, tachycardia, bloat, convulsions, coma and death. In the current study the acute toxicity was determined by intra-peritoneal injections of the aqueous extracts from different plant parts in a total of one hundred and fifty (150) white Swiss mice aged between to and 12 weeks and divided in groups of six (3 males and 3 females) for each dosage level. The median lethal dose (LDso) was then calculated by the method of Reed and Muench (1938). The subacute toxicity was determined by feeding five groups of two male Friesian calves each, aged between 8 and 10 months, at 0 (control), 4, 8, 16 and 32% levels of dried ground whole plant material in wheat bran for 14 weeks. The physiological parameters of rectal ...
Mortality data for C57BL mice and Sprague-Dawley rats were collected as a part of the program to biologically characterize AFRRI-TRIGA reactor radiations and to provide reference information for future studies. Unilateral whole body exposures to mixed gamma-neutron radiations from the reactor or to 250 kVp x rays were carried out over a range of midline tissue doses from 370 to 875 rads. The 30-day median lethal doses were calculated to be 589 and 432 rads for mice exposed to the x rays and to the reactor radiations, respectively. The corresponding values for the rat exposures were 740 and 434 rads. Using the LD50/30 values as the end points for comparison, the reactor radiations were 1.4 and 1.7 times more effective in mice and rats, respectively, than were the x rays. The survival times of the mice and rats exposed to reactor radiations were significantly less than those of the animals exposed to similar doses of x rays.

Todays graphic is a whimsical look at lethal doses of chemicals we consume on a regular basis. Whilst it may be more common to view chemicals in a black and white framing of toxic or non-toxic, the reality is more of a sliding scale of toxicity. The admission of too much of any chemical into the body can cause toxic effects, and even death - the only variant from chemical to chemical is how much is too much. For some chemicals, the amount will be very low, whilst for others, it may be almost impossibly high.. So, how can we compare the toxicities of differing chemicals, when they can all produce varying effects, and these effects all require the intake of differing amounts? One of the most commonly quoted figures when discussing the toxicity of chemicals is the LD50, which stands for lethal dose 50%, or median lethal dose. This is the amount of a chemical required to cause death in 50% of the animals in the group it is tested on. The figures can be given for when the chemical is given ...

Intestinal or injection infection are rarer, but the prognosis for all infections are generally considered poor. Anthrax toxin is one of the most lethal toxins known. To make matters worse, anthrax endospores are notoriously hard to sterilize, resulting autoclaving for smaller heat-resistant equipment, irradiation for items such as letters or packages, and gas treatment for infected buildings. Anthrax has gained notoriety because it is a very good bioweapon with low median lethal dose and quick infection periods, as well as the ability to form endospores. These spores may persist in soil for years, making it easily spread among livestock. In 2001, a terrorist plot involving anthrax spore-seeded letters mailed to US Senators killed postal workers and led to a complete cleanup of several facilities. In addition, it is known that the Soviet Unions bioweapons program developed many highly contagious strains of anthrax and other infectious diseases.

Downloadable! Trade theory traces back different patterns of internationalization to heterogeneity between firms, measured both through differences in productivity levels and size. In this paper we analyze the link-between heterogeneity within sectors and internationalization choices, namely trade and foreign di-rect investments (FDI) for a large sample of countries and industries between 1994 and 2004. The focus of our paper is on the role played by average productivity level and the distribution of firms by size in explaining differences across sectors and countries in the extensive margin of internatio-nalization (i.e., the number of foreign nations where firms from a given sector and country have ex-panded abroad). By performing an ordered probit analysis, and controlling for other factors affect-ing the patterns of internationalization, we confirm that industries with higher productivity levels and with a distribution of firms shifted toward large firms are more prone to internationalize in for
The remarkable Graham method for visualization of gall bladder since its discovery in 1923 (1) is now widely used as a routine procedure in the Roentgen diagnosis of gall bladder conditions. The high toxicity of the tetrahalogenophenolphthaleins employed in this test is well known as evidenced by the reports of some marked constitutional reactions after the administration of the drug sometimes observed in the earlier days of the development of this method of diagnosis. With the improvement of technique of administration and of purer preparation of the salts, however, any untoward effect has been eliminated. The substitution for the tetrabromphenolphthalein ...

Chemical agents are poisonous vapors, aerosols, liquids and solids that have toxic effects on people, animals or plants. Chemical agents can cause death but are difficult to deliver in deadly amounts because they dissipate quickly outdoors and are hard to produce. Before a Chemical Emergency A chemical attack could come without warning. Signs of a chemical release include difficulty breathing, eye irritation, loss of coordination, nausea or burning in the nose, throat and lungs. The presence of many dead insects or birds may indicate a chemical agent release.

Toxicological studies Acute toxicity studies The acute toxicity of amitrole to several animal species is given in Table 1. No signs of toxicity were observed in one beagle-type female dog when given amitrole (96.1%) by gavage at a dosage of 2150 mg/kg bw. Another dog receiving 4640 mg/kg bw vomited within 1 hour, and no signs of toxicity were observed thereafter (Fogleman, 1954). When a commercial product (water soluble powder with 50% active ingredient) was administered to mice, the LD50 was reduced to 4.0 g/kg bw amitrole. By determining the mean lethal dose for amitrole in different preparations, it was established that sodium carbonate, sodium bicarbonate and wetting agents as admixtures in various quantities considerably increase the toxicity of amitrole (Hapke, 1967). WHO has classified amitrole as unlikely to present acute hazard in normal use (WHO, 1992). Table 1.

Based on mammalian median lethal dose (LD50) rating of 2,660 mg/kg body mass, boric acid is poisonous if taken internally or inhaled in large quantities. The Thirteenth Edition of the Merck Index indicates that the LD50 of boric acid is 5.14 g/kg for oral dosages given to rats, and that 5 to 20 g/kg has produced death in adult humans. For comparisons sake, the LD50 of salt is reported to be 3.75 g/kg in rats according to the Merck Index.. Long term exposure to boric acid may be of more concern, causing kidney damage and eventually kidney failure (see links below). Although it does not appear to be carcinogenic, studies in dogs have reported testicular atrophy after exposure to 32 mg/kg bw/day for 90 days. This level is far lower than the LD50.[5]. According to boric acid IUCLID Dataset published by the European Commission, boric acid in high doses shows significant developmental toxicity and teratogenicity in rabbit, rat, and mouse fetuses as well as cardiovascular defects, skeletal variations, ...

The International Tanker Owners Pollution Federation3 lists effects of oil spills (see http://www.itopf.com/). Noted is the following: The most toxic components in oil tend to be those lost rapidly through evaporation when oil is spilled. The lethal concentrations of toxic components leading to large scale death of marine life are relatively rare, localized and short-lived. Sub-lethal effects may impair the ability of marine organisms to reproduce, grow, feed or perform normal functions caused by prolonged exposure to a concentration of oil or oil components far lower than will cause death. Oysters, mussels and clams living in shallow waters routinely filter large volumes of seawater to obtain food and are more likely to accumulate oil components. While these components may not cause any immediate harm, their presence may render such animals unappetizing if they are consumed with the presence of an oily taste or smell. This is a temporary problem since the components causing the off taste are ...

Cancer is the second leading cause of death in the USA, following cardiovascular disease. Treating cancer using conventional therapies is associated with low response rates and high toxicity, because these therapies usually lack specific tumor accumulation. Loading anticancer drugs into intelligently designed polymeric nanoparticles (NPs) can serve in delivering these drugs specifically to the tumor site, thus boosting their efficacy and reducing any associated off target toxicity. Targeting NPs to the tumor site can occur through either passive or active means. In passive targeting, NPs of specific size and surface characteristics can exploit the tumors erratic vasculature and occluded lymphatic drainage to extravasate the systemic circulation and accumulate preferentially at the tumor site. Active targeting mandates grafting the surface of NPs with a ligand that specifically interacts with a protein expressed at higher levels at the tumor site, in comparison to elsewhere in the body. In the current
