please give me correct ans.

Explanation:
Health Effects

Pesticides have been linked to a myriad of diseases. The Pesticides Literature Review, which is based on studies conducted by a multi-university research team in Toronto, concludes, "people should reduce their exposure to pesticides because of links to serious illnesses. Results of this study found consistent evidence of serious health risks such as cancer, nervous system diseases and reproductive problems in people exposed to pesticides…through home and garden exposure."
Similar research has linked exposure to pesticides to increased presence of neurological disorders, Parkinson’s disease, childhood leukemia, lymphoma, asthma and more. Progressing to organic repellents is a logical step to potentially help reduce the chances of disease or disease acceleration.
Remnants of pesticides have been found in the bloodstream of certain types of cancer sufferers. In The Facts About Organic Foods; Having More Vitamins and Minerals Protects You From Chronic Disease, James Cleeton claims that "women with breast cancer are five to nine times more likely to have pesticide residues in their blood than those who do not. The apparent link between hormone dependent cancers, such as those of the breast and prostate, may be via endocrine disrupting chemicals such as 2,4D and Atrazine (both herbicides)."
With daunting statistics like these, why not make the move to organic-listed repellents? You too can choose to enjoy a pretty, critter-free lawn and garden without using potentially harmful chemic
Answer:
Direct impact on humans
If the credits of pesticides include enhanced economic potential in terms of increased production of food and fibre, and amelioration of vector-borne diseases, then their debits have resulted in serious health implications to man and his environment. There is now overwhelming evidence that some of these chemicals do pose a potential risk to humans and other life forms and unwanted side effects to the environment (Forget, 1993; Igbedioh, 1991; Jeyaratnam, 1981). No segment of the population is completely protected against exposure to pesticides and the potentially serious health effects, though a disproportionate burden, is shouldered by the people of developing countries and by high risk groups in each country (WHO, 1990). The world-wide deaths and chronic diseases due to pesticide poisoning number about 1 million per year (Environews Forum, 1999).
Impact through food commodities
For determining the extent of pesticide contamination in the food stuffs, programs entitled ‘Monitoring of Pesticide Residues in Products of Plant Origin in the European Union’ started to be established in the European Union since 1996. In 1996, seven pesticides (acephate, chlopyriphos, chlopyriphos-methyl, methamidophos, iprodione, procymidone and chlorothalonil) and two groups of pesticides (benomyl group and maneb group, i.e. dithiocarbamates) were analysed in apples, tomatoes, lettuce, strawberries and grapes. An average of about 9 700 samples has been analysed for each pesticide or pesticide group. For each pesticide or pesticide group, 5.2% of the samples were found to contain residues and 0.31% had residues higher than the respective MRL for that specific pesticide. Lettuce was the crop with the highest number of positive results, with residue levels exceeding the MRLs more frequently than in any of the other crops investigated. The highest value found in 1996 was for a compound of the maneb group in lettuce which corresponded to a mancozeb residue of 118 mg/kg. In 1997, 13 pesticides (acephate, carbendazin, chlorothalonil, chlopyriphos, DDT, diazinon, endosulfan, methamidophos, iprodione, metalaxyl, methidathion, thiabendazole, triazophos) were assessed in five commodities (mandarins, pears, bananas,beans, and potatoes). Some 6 000 samples were analysed. Residues of chlorpyriphos exceeded MRLs most often (0.24%), followed by methamidophos (0.18%), and iprodione (0.13%). With regard to the commodities investigated, around 34% contained pesticide residues at or below the MRL, and 1% contained residues at levels above the MRL. In mandarins, pesticide residues were most frequently found at levels at or below the MRL (69%), followed by bananas (51%), pears (28%), beans (21%) and potatoes (9%).
