Twenty-four brands of plastic baby feeding bottles were purchased and all were found to be made of polycarbonate. Taking a batch of one representative sample, the polymer was tested for stability and possible release of bisphenol A following domestic practice of sterilization. Sterilization was by alkaline hypochlorite, steam, or washing …
Migration of bisphenol-A (BPA), the principal monomer of polycarbonate (PC) baby bottles, was investigated using an aqueous migration simulant. BPA was determined in 200 mL water samples using stir bar sorptive extraction (SBSE) after in situ derivatization with acetic acid anhydride followed by thermal desorption (TD)-capillary GC-MS. The concentration of …
A comprehensive migration database was established for bisphenol A from polycarbonate baby bottles into water during exposure to microwave heating. Eighteen different brands of polycarbonate baby bottles sold in Europe were collected. Initial residual content of bisphenol A and migration after microwave heating were determined. Residual content of bisphenol A …
Studies carried out by a team of scientists at the Indian Institute of Spices Research (IISR) have revealed high levels of phosphorus in the soil samples from Kozhikode and Wayanad districts. Overuse of chemical fertilisers and neglect towards soil test-based fertiliser recommendations have resulted in imbalances in the nutrient levels …
A sampling of products sweetened with organic brown rice syrup, including cereal bars and baby formulas, found levels of arsenic that exceeded the United States’ standards for bottled water, American researchers said on Thursday. The study by researchers at Dartmouth College in New Hampshire followed a Consumer Reports analysis of …
Genetically modified crops or organisms (GMOs) are produced by the now well-known branch of molecular biology, the recombinant DNA technology or genetic engineering. The share of GM crops in world agriculture is increasing steadily. From 1996 to 2009, the cultivation of GM crops has seen an 80-fold increase. In India, …
Male mating signals, including ornaments and courtship displays, and other sexually selected traits, like male-male aggression, are largely controlled by sex hormones. Environmental pollutants, notably endocrine disrupting compounds, can interfere with the proper functioning of hormones, thereby impacting the expression of hormonally regulated traits. Atrazine, one of the most widely …
In 2009, the promulgation of US Food and Drug Administration (FDA) tobacco regulation focused attention on cigarette flavor additives. The tobacco industry had prepared for this eventuality by initiating a research program focusing on additive toxicity. The objective of this study was to analyze Philip Morris' Project MIX as a …
Greenhouse pot culture studies were conducted to evaluate the bioremediation potential of spinach for removal of cadmium. The results indicated that spinach was able to take up cadmium in substantial quantity in the shoot. There were no visual cadmium toxicity effects on spinach and no significant reduction in the dry …
The omnipresent group of pesticide adjuvants are often referred to as “inert” ingredients, a rather misleading term since consumers associate this term with “safe”. The upcoming new EU regulation concerning the introduction of plant protection products on the market (EC1107/2009) includes for the first time the demand for information on …
More than two years after leading health and parents' groups asked Johnson & Johnson to reformulate its flagship baby shampoo to remove a cancer-causing chemical, the company is still using formaldehyde-releasing preservatives in Johnson's Baby Shampoo in some countries (including the U.S.), while formulas sold in other countries are free …
Diesel exhaust particles (DEPs) are the main components of ambient particulate materials, including polyaromatic hydrocarbons (PAHs), n-PAHs, heavy metals, and gaseous materials. Many epidemiological, clinical, and toxicological studies have shown that ambient particles, including DEPs, are associated with respiratory disorders, such as asthma, allergic rhinitis, and lung cancer. However, the …
The book throws light on classification of pesticide active ingredients on the basis of their toxicity to non-target organism by latest WHO covering information on all the 230 pesticides registered in India as on May, 2011. It includes trade name, registered formulations, target pests and crops which they are applied …
EXPOSURE to organic pollutants can disrupt the formation of nervous system in a foetus. This in turn may lead to neural tube defects. The disease affects over 320,000 infants worldwide every year. Earlier studies have linked organic pollutants like polycyclic aromatic hydrocarbons (PAHs), from indoor coal stoves, smoking and vehicle …
Patancheru, near Hyderabad, India, is a major production site for the global bulk drug market. Approximately 90 manufacturers send their wastewater to a common treatment plant in Patancheru. Extraordinary high levels of a wide range of pharmaceuticals have recently been demonstrated in the treated effluent. As little as 0.2% of …

A method for the concurrent determination of methyl mercury and inorganic mercury by flameless atomic absorption spectroscopy (AAS) is described. Fifty-seven samples of juvenile black marlin fish were analyzed for inorganic and methyl mercury, and total mercury was calculated by addition of the 2 values. The sensitivity of the method …
Methods of digestion of fish samples for mercury determination by flameless atomic absorption spectrophotometry have been investigated. Digestion in Teflon bombs, Kjeldahl flasks, or borosilicate test tubes gives comparable precisions and mercury recoveries. Because of their cost and effect in limiting productivity, Teflon bombs were considered unnecessary for analysis of …
THE Supreme Court has turned down the request of pesticide manufacturers to allow them to export the pesticide stocks in India. The court had banned the sale, manufacture, use and export of the pesticide on May 13 on a petition by the youth wing of the CPI(M), the Democratic Youth …
