Project 31 : Visit a local distributer of chemical pesticides and make a detail list of commonly used pesticides in the area and used for which crops. Write about their impacts on human health and environment. is an officially approved project topic in the Maharashtra State Board Class 12 Environmental Studies and Water Security curriculum. This comprehensive study equips students with practical field methodologies, ecological analysis, and empirical data required for securing an 'A' grade in school/junior college internal assessments.
Environmental Education and Water Security emphasizes sustainable development through scientific investigation. The practical documentation provided below covers the core findings, observations, and policy measures needed for comprehensive academic evaluation.
Aim of the Study: To visit a licensed agricultural pesticide retail distributor / Krishi Seva Kendra, compile a comprehensive inventory of bestselling chemical pesticides and insecticides, identify target crops, and evaluate severe ecotoxicological impacts on human health and ecosystems.
Field interview with a licensed agrochemical dealer, recording product label specifications, photographing chemical toxicity warning triangles, and cross-referencing against Central Insecticides Board (CIBRC) toxicology databases.
This scientific investigation conforms strictly to Maharashtra State Board practical guidelines, incorporating primary survey data, empirical observations, and practical field documentation.
The following empirical observation matrix demonstrates standard data collection parameters, field measurements, and recorded outcomes for this project study:
| Commercial Brand & Active Ingredient | Chemical Class & Toxicity Color | Primary Target Crops | Pests / Weeds Targeted | Human Health & Environmental Hazard |
|---|---|---|---|---|
| Monocrotophos 36% SL | Organophosphate (Red Triangle - Extremely Toxic) | Cotton, Paddy, Vegetables | Bollworms, sucking pests, leafhoppers | Potent neurotoxin; inhibits acetylcholinesterase; causes paralysis and fatal respiratory failure; lethal to birds. |
| Chlorpyrifos 20% EC | Organophosphate (Yellow Triangle - Highly Toxic) | Sugarcane, Cotton, Citrus | Termites, stem borers, white grubs | Severe developmental neurotoxicity in children; endocrine disruptor; highly toxic to fish and aquatic life. |
| Imidacloprid 17.8% SL | Neonicotinoid (Blue Triangle - Moderately Toxic) | Cotton, Tomato, Okra, Chilly | Aphids, whiteflies, thrips, jassids | Systemic neurotoxin; primary cause of global honeybee Colony Collapse Disorder; disrupts pollinator navigation. |
| Profenofos 40% + Cypermethrin 4% | Mix OP + Pyrethroid (Yellow - Highly Toxic) | Cotton, Soybean, Vegetables | Bollworms, Spodoptera caterpillars | Severe eye and skin corrosion; acute inhalation toxicity; bioaccumulates in aquatic food chains. |
| Glyphosate 41% SL | Organophosphonate Herbicide (Blue Triangle) | Tea plantations, Fallow land, Bunds | Non-selective systemic broad-spectrum weeds | Classified by WHO (IARC) as Group 2A 'probably carcinogenic to humans'; destroys beneficial soil mycorrhizal fungi. |
The field study and investigation of Project 31 focuses on the following key environmental observations and highlights:
A comprehensive analysis of Project 31 reveals crucial insights regarding agrochemical ecotoxicology and local ecological resilience. By examining empirical data collected in the field, students understand the direct impact of human activity on ecosystems and learn practical conservation strategies applicable to Maharashtra's local environment.
Chemical pesticides are biological weapons sold over the counter. Their careless, unmonitored spraying poisons farm laborers, exterminates vital pollinator honeybees, leaves toxic residues in our daily vegetables, and contaminates deep aquifers. Promoting organic bio-pesticides is an urgent public health imperative.
To secure full marks (30/30) in your internal project evaluation, structure your handwritten project file in the following official order:
Red = Extremely Toxic (Highest danger); Yellow = Highly Toxic; Blue = Moderately Toxic; Green = Slightly Toxic.
It is an inexpensive, highly effective broad-spectrum insecticide, but its extreme toxicity causes hundreds of farmer poisoning fatalities annually in developing nations.
Protective chemical-resistant clothing including face respirators, rubber gloves, goggles, rubber boots, and full-body aprons to prevent dermal and inhalation exposure.
Neonicotinoids are systemic chemicals absorbed by plants that contaminate flower nectar and pollen; when bees consume it, their nervous systems are damaged, causing memory loss, disorientation, and hive collapse.
Immediately remove the person from the contaminated field into fresh air, wash affected skin with soap and plenty of water, induce vomiting only if advised on the label, and rush to a hospital with the chemical container for immediate antidote administration (e.g., Atropine for organophosphates).
