Bottles can be toxic- Part II
In spite of the prohibition on the use of Bisphenol-A (BPA) in baby feeding bottles, the toxic chemical continues to be found in some baby products sold in the Indian market. BPA is an endocrine disrupting

The Bhopal gas tragedy: An environmental disaster
The multi-disciplinary study of histopathology and toxicology of Bhopal gas tragedy resolved several issues. First, the progression of severe pulmonary oedema to chronic fibrosis was confirmed experimentally, following a single exposure to MIC. Analysis of the residue in Tank 610 revealed over 21 chemicals.

Increased migration levels of bisphenol A from polycarbonate baby bottles after dishwashing, boiling and brushing
Baby bottles are often made of polycarbonate plastic. Impurities remaining in the bottle from the monomer bisphenol A can migrate from the plastic bottles into baby food, thereby causing a health concern.

Polychlorinated dibenzo-p-dioxins, dibenzofurans, and polychlorinated biphenyls in human tissues, meat, fish, and wildlife sampl
Concentrations of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and non- and mono-ortho-substituted polychlorinated biphenyls (dioxin-like PCBs) were measured in tissues of humans, fishes, chicken, lamb, goat, predatory birds, and Ganges River dolphins collected from various locations in India.

Sources and accumulation of butyltin compounds in Ganges River Dolphin, Platanista gangetica
Concentrations of butyltin compounds (mono-, di-, and tri-butyltin) were determined in dolphin (Platanista gangetica), fish, invertebrates and sediment collected from the River Ganges, India, in order to understand the contamination levels, sources, and potential for biomagnification in freshwater food chains.

Analysis of potentially toxic phthalate plasticizers used in toy manufacturing
A plasticizer is a substance normally incorporated to a PVC resin or some other materials such as paints, to improve some of its properties as flexibility or processability. Phthalates, adipates, phosphates and some others are the main compounds used as plasticizers. Some of these compounds, as bis-(2-ethylhexyl)

Determination of Bisphenol-A in reusable polycarbonate food-contact plastics and migration to food-simulating liquids
Bisphenol-A (BPA) is a principal reactant in the preparation of polycarbonate (PC) plastics and has been shown in in vitro cell proliferation studies to exhibit estrogen-like characteristics. Reusable

Investigations into the potential degradation of polycarbonate baby bottles during sterilization with consequent release of bisphenol A
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

The neurobehavioural toxicity of endosulfan in rats: a serotonergic involvement in learning impairment
<p>Oral administration of the insecticide endosulfan (2 mg/kg per day) for 90 days in immature male rats resulted in an inhibition of pole-climbing escape response to electric shock (unconditioned) and avoidance response to buzzer (conditioned). These responses reflect respectively their learning and memory processes.

The International Medical Commission on Bhopal: Findings & recommendations
In addition to the large-scale loss of life and continuing health problems experienced by the victims of the Bhopal disaster, a major casualty has been the lack of information. Compared to other major chemical disasters in the world, Bhopal has the dubious distinction of not only being the worst, but also one of the least investigated.

Persistent organochlorine residues in foodstuffs from India and their implications on human dietary exposure
Foodstuffs collected from different regions in India were analyzed for the presence of HCH (BHC), DDT, HCB, aldrin, dieldrin, heptachlor, and PCBs. Significantly high levels of food contamination with HCH, DDT, aldrin, and dieldrin were evident throughout India. Dairy products and livestock meat are the prime sources of human dietary exposure to these chemicals.
