This study examined cancer mortality risks associated with occupational exposures to rubber dust, rubber fumes and nitrosamines in a large occupational cohort of UK rubber manufacturing workers with 49 years of follow-up (880 794 person years). We found increased risks associated with cumulative exposures to rubber dust, rubber fumes and N-nitrosamines, which can be attributed to the unique combination of very long follow-up of the cohort, 94% mortality and selection of the exposures based on prior knowledge on carcinogenicity.1 Linear exposure-response relationships were found for cumulative exposure to NDMA (bladder, stomach, leukaemia, multiple myeloma, prostate, liver), NMor (bladder, stomach, multiple myeloma, oesophagus, prostate, pancreas) and rubber dust (lung). Plateauing exposure-response relationships were found for rubber dust (leukaemia), rubber fumes (lung, leukaemia, multiple myeloma, oesophagus, prostate, pancreas), NSS (bladder, lung, leukaemia, multiple myeloma, prostate) and ...
Because of this relationship, the rubber plant does not produce highly colourful or fragrant flowers to attract other pollinators. Its latex sap was once used in rubber production! Will it grow? If your rubber plants stems are turning brown, unfortunately something is definitely amiss and your plant needs immediate care. The rubber plant is part of the well-known Ficus (or Fig) family. When this plant is about 1 - 2ft tall its well suited sitting as a centrepiece on a table, on a shelf, or on a windowsill, but once it begins to grow above 3ft it looks great standing next to a fireplace, television area or near door entrances (as longs as their are no cold drafts). If you still need to cut back a leggy rubber plant after the air layering process, cut off the remaining bare stem about five inches above the soil line and add some fresh soil to the pot. Reply. From May - June re-pot once the roots have become pot bound or every year when the plants are very young, and then once every 3 years after ...

Over the centuries, rubber latex gained its popularity in machinery application due to its unique thermal properties, high elasticity and excellent impact resistance. It is widely accepted in food industry as rubber has good resistance to chemicals, including acids, alkalis and salts. For instance, rubber components comprise of couplings, shields, dust covers, gaskets and seals exist as group or standalone component in food manufacturing equipments or machinery. Even though most of the rubber based products in food industry fulfil the requirements of Food and Drug Administration (FDA), however, the presence of trace amount of chemicals upon the preceding processing of rubber might accidentally contaminate to the food products.

In our modern cities, roads make up about one-fifth of the urban land area, and about half of the impervious surfaces. On these roads we have driven our cars and trucks with inflatable rubber tyres for over a century. These rubber tyres wear, and have to be regularly replaced.. Sometimes the rubber comes off in a dramatic cloud of smoke when the car skids on the road. Sometimes the road surface is sharp and slices fragments out of the rubber. But most of the time, in the course of normal rotation without skidding or cutting, the rubber is compressed and then expands. As it compresses and expands, tiny cracks develop and spread in the tread - and tiny particles of rubber flake off. How much rubber dust is there, where does it go, and is it harmful?. Each time a tyre rotates, it loses a layer of rubber about a billionth of a metre thick. If you do some numbers, this works out to about four million million million carbon atoms lost with each rotation.. A busy road with 25,000 vehicles travelling on ...

Dandelion rubbers quality and performance are nearly identical to that produced by Hevea rubber trees grown in Southeast Asia.. Turning dandelions into an industrial rubber crop will require further trait development to make it easier to grow and higher yielding. European researchers and companies are also working on improved varieties and processing technologies. They all share the same goal: finding a nontropical alternative to the venerable rubber tree.. People have been looking for an alternative rubber producing plant ever since Henry Ford: dandelions, goldenrod and sunflower. Whenever war, weather or disease makes natural rubber expensive, people start looking for alternatives. But the crises never last long enough for a new crop to gain a toehold.. Now, dandelion rubber proponents say long-term concerns about prices , sustainability and labor availability are strong enough to develop dandelion rubber seriously. Trees on rubber plantations in south east Asia take years to grow to ...

Soil respiration (SR) plays an important role in the global carbon cycle. The widespread and continued conversion of tropical forests to plantations is expected to drastically alter CO2 production in soil, with significant consequences for atmospheric concentrations of this crucial greenhouse gas. In Southeast Asia, rubber plantations are among the most widespread monoculture tree plantations. However, knowledge of how SR differs in rubber plantations compared to natural forests is scarce. In this study, surface CO2 fluxes and soil CO2 concentrations (at 5 cm, 10 cm, 30 cm and 70 cm depths) were measured at regular intervals over a one-year period along slopes at three sites in paired natural tropical forests and mature rubber plantations. Annual surface soil CO2 fluxes were 15% lower in the rubber plantations than in natural forest. This difference was due to substantially lower SR during the dry season in rubber plantations compared to natural forest. During the wet season, SR did not differ ...
article{0e81fc50-5659-446c-9bfd-c697cf571066, abstract = {Objectives Workers in the rubber industry are exposed to a complex mixture of hazardous substances and have increased risk of developing several diseases. However, there is no up to date survey examining the exposure in the Swedish rubber industry. One of the toxic compounds in the industry is carbon disulfide (CS2), which is biotransformed to 2-thiothiazolidine- 4carboxylic acid (TTCA). TTCA is used as a biomarker of CS2 exposure, but there seem to exist inter- and intraindividual variability; which could partly be due to genetic variation. The aim of the study was to determine TTCA levels and the modifying effects of glutathione-related genes in a group of Swedish rubber workers. Methods Urine was collected from both exposed workers and controls during the last 4 h of the work shift. The level of TTCA in urine was analyzed by liquid chromatograpy tandem mass spectrometry.

Back , Main menu , PSLC In 1839 Charles Goodyear invented a process called vulcanization, which made rubber more durable and more useful at hot and cold temperatures. Vulcanization crosslinks rubber. That is, it ties all the chainlike rubber molecules together to form one big molecule. This does a lot for the rubber, but it can also make rubber difficult to process. Think about it. A material made of one molecule cant really flow into a mold, and it cant be shaped or worked very easily. A material made of crosslinked rubber has to be shaped before it is crosslinked. Crosslinking also makes rubber difficult to recycle. Some kinds of synthetic rubber arent crosslinked, however. They can be molded and remolded again and again. They are called thermoplastic elastomers. Thermo- means heat, and plastic means moldable. Elastomer is just a fancy word that means rubber. So a thermoplastic elastomer is a rubber that can be molded when it is heated. While it is wonderful that thermoplastic ...
