One body, multiple pathways: where India is going wrong in regulating pesticide exposure

Political & Constitutional Dimensions: The article implicitly critiques the executive's regulatory approach under existing statutes like the Insecticides Act, 1968, and the Water Act, 1974. The government's position, as reflected in Rajya Sabha responses, is that the proportion of samples exceeding MRLs (2.8% in recent data) remains low, suggesting the system is effective. The opposition and civil society groups, however, argue that this metric is misleading because it does not account for cumulative exposure. From a constitutional perspective, this touches upon the directive principles under Article 47 (duty of the state to raise the level of nutrition and the standard of living and to improve public health) and Article 21 (right to life), which has been interpreted to include the right to a healthy environment. The federal nature of the issue is also significant: while central bodies like CIB&RC and FSSAI set standards, implementation and monitoring of groundwater and water quality fall on state governments and their pollution control boards, leading to uneven enforcement.

Economic & Financial Impact: The article does not provide specific figures on the economic cost of pesticide exposure, but several implications can be inferred. The health burden from chronic diseases linked to pesticide exposure (e.g., cancer, neurological disorders) translates into increased healthcare expenditure for both individuals and the state. The 2023 ICMR study from Telangana and the 2025 West Bengal study point to significant risks among farming and elderly populations, who often have limited access to healthcare. On the agricultural side, the continued use of pesticides, especially those that are not yet banned, has economic benefits for the agrochemical industry. The government's decision to ban or phase out 46 pesticides (announced in 2023) may have short-term economic costs for farmers who need to switch to alternative pest control methods, but long-term benefits from reduced health spending and environmental remediation. The lack of cumulative exposure data means the true societal cost is likely undervalued, leading to underinvestment in regulatory reform.

Social Dimensions: The social impact is highly inequitable. The article highlights that the most affected populations are often rural, agricultural communities with limited access to healthcare and low awareness of pesticide hazards. The example of Bhuttiwala village in Punjab's Malwa region—where 18 of 20 identified cancer patients died within eight months—illustrates the acute social deprivation in such areas. The endosulfan case in Kasaragod, Kerala, where over 3,000 children have been recorded with congenital disabilities, shows intergenerational harm. The West Bengal study (2025) finds cognitive impairment and movement disorders at higher rates in elderly populations exposed to pesticides, indicating a long-term social care burden. The indoor air pathway further suggests that urban populations, especially those using repellents and aerosol insecticides, are also at risk, though this is less monitored. Thus, the issue cuts across rural-urban lines but disproportionately affects the rural poor.

Governance & Administrative Aspects: The article identifies a fundamental governance failure: the absence of an integrated monitoring framework. The existing system—Food MRls by FSSAI, water quality by CPCB/State boards, air quality by CPCB—operates in silos. There is no single agency responsible for measuring cumulative human exposure through all three pathways. The administrative challenge is compounded by data gaps, especially for air and indoor environments, where "a pathway nobody measures is a pathway nobody can regulate." The lack of coordination between the Ministry of Agriculture (which bans pesticides based on efficacy and safety), the Ministry of Health (which monitors food MRLs), and the Ministry of Environment, Forest and Climate Change (which oversees water quality) is a classic example of sectoral fragmentation. Additionally, the federal structure means that even if a central body like the ICMR conducts biomonitoring studies (as it did in Telangana and West Bengal), translating findings into regulatory action at the state level remains a challenge.

International Perspective: The article references the U.S. Environmental Protection Agency (EPA) noting that indoor pollutant concentrations can be two to five times higher than outdoors. This points to a global recognition of multi-pathway exposure, which India lacks. Internationally, many developed countries have moved towards cumulative risk assessment (CRA), which evaluates the combined health risk from exposure to multiple chemicals through multiple routes. The European Union's Regulation (EC) No 1107/2009, for example, requires consideration of cumulative and synergistic effects when approving pesticides. India's continued reliance on single-pathway, single-chemical MRLs makes it an outlier in this regard. The lack of comprehensive biomonitoring—where blood and urine samples are systematically tested for pesticide metabolites—further puts India behind global best practices that use such data to inform regulation.
