In a monitoring study residue levels of organochlorines (OC), synthetic pyrethroids (SP), organophosphates (OP) and carbamates were determined in unprocessed and processed three vegetables viz. brinjal, cauliflower and okra to know the residue levels and evaluate the effect of different household processes (washing and boiling/cooking) on reduction of residues.
Environmental contaminations by organochlorine pesticides (OCPs) of inland water have been a global issue, since most of these compounds are very persistent, bioaccumulative and toxic compounds.
Pesticides are notorious contaminants due to their toxic and carcinogenic nature and, unfortunately, are distributed globally in air, water, sediment, soil and foods even to the places where they have not been used before. SPE and GC methods were developed to analyze organochlorine pesticides.
A solid phase extraction and gas chromatography with negative chemical ionization mass spectrometry in scan mode (GC-NCI-MS) method was developed to identify and quantify for the first time low levels of organochlorine pesticides (OCs) in plasma samples of less than 100 ?l from wild birds.

In Poland honey has never been included in regular pesticide residues controls. Because no maximum residues levels (MRLs) have been established for pesticides in honey it is very hard to evaluate the contamination of honey with pesticides and the possible damage to human health.
In December 2005, CSE's Pollution Monitoring Lab decided to check whether the samples of soft drinks available in the market are within the limits prescribed by BIS or not. A total of 57 samples, of 11 brands of Pepsi Co and Coca Cola available in the market, were collected from 12 different states of the country.
The occurrence of organochlorine compounds in the food chain has already been reported in several studies. This class of organic compounds constitutes one of the most important groups of dangerous organic contaminants.
Concentrations of polychlorinated biphenyls (PCBs), DDT and its metabolites (DDTs), HCH isomers (HCHs), chlordane compounds (CHLs) and hexachlorobenzene (HCB) were determined in sediment, soil, whole body homogenates of resident and migratory birds and their prey items (including fish, green mussel, snail, earthworm, crabs, prawn, lizard and frogs), bird eggs and bats collected from southern India
