Assessment of Ambient Air Quality during Pre-Diwali, Diwali and Post-Diwali Festival, 2017
CSIR-Indian Institute of Toxicology Research (CSIR-IITR), Lucknow conducted Air Quality
survey at 7 locations (Aliganj, Vikasnagar, Indiranagar, Gomtinagar, Charbagh, Aminabad and
Chowk) of Lucknow city to assess the impact of fireworks on the environment during the Diwali
festival, 2017. Monitoring results revealed that the respirable particulates during pre-Diwali,
Diwali and post-Diwali are well above the National Ambient Air Quality Standards of 60 and
100 µg/m3 for PM2.5 and PM10 respectively.

Assessment of Ambient Air Quality of Lucknow City during Pre-Monsoon: Findings of a Random Survey (Report Released on World Environment Day, 2017)
The study was carried out during the months of April-May, 2017 to assess the status
of air quality by monitoring and assessment of some selected air pollutants namely
Respirable Suspended Particulate Matter (RSPM or PM10), Fine particles (PM2.5),
Sulphur Dioxide (SO2), Oxides of Nitrogen (NOx) and trace metals-Lead (Pb) and
Nickel (Ni)and noise level at 9 representative locations, categorized as residential
(four), commercial (four) and industrial (one) areas in Lucknow city. The results
revealed the 24 hours concentration of PM10 to be in the range of 140.5 to 310.6
µg/m3 with an average of 222.8 µg/m3
. The 24 hours concentration of PM2.5 was
found to be in the range of 66.7 to 169.0 µg/m3 with an average of 109.4 µg/m3
average values of PM10 and PM2.5 irrespective of locations were found to be above the
permissible limit (100 µg/m3
for PM10 and 60 µg/m3
for PM2.5 prescribed by MoEF).
Twenty four hours concentration of SO2 and NOx were found to be in the range of 6.8
to 16.7 and 25.7 to 97.8 µg/m3 with an average concentration of 11.7 and 49.7 µg/m3
respectively and all the values were below the permissible limits (80 µg/m3
mean level of trace metals were Pb = 219.97 and Ni = 48.34 ng/m3
. Noise levels
during day and night time were found to be in the range of 65.8 to 81.4 dB (A) and
56.3 to 67.4 dB (A) respectively which was above the respective permissible limits
except in industrial area.

With a view to fulfil the ultimate objective of inclusive growth by helping in improving the quality of life of people, AcSIR has mandated that the students aspiring to obtain a Ph.D. degree from the Academy undertake a 6-8 weeks project concerned with societal/rural issues under the CSIR-800 programme. The intent is to create and nurture a sense of social consciousness and responsibility by participation in Science & Technology activities relevant to the nation.
The programme is aimed at improving the quality of lives of people through initiatives that are socially and economically relevant. Accordingly, the two major focus areas are:
Enhancing Income of the downtrodden
To Improve Quality of Life
- Value added Agriculture
- Waste to Wealth
- Energy efficiency
- Low cost housing
- Affordable health care
- Potable Water supply
- Sustainable energy
- Means of protecting environment
Under this programme, students select a scientific topic of social relevance and aligned with the focus areas of CSIR-800 and study the problem in detail. Thereafter, they are expected to suggest remediation measures which are techno-commercially viable and have the potential to be scaled up to uplift the quality of life of the population at large. Towards this direction, twenty-two AcSIR-IITR students visited various rural areas in the states of Uttar Pradesh, Madhya Pradesh, Bihar and Jharkhand for disseminating information and creating awareness on diverse problems prevalent in our society. Some of the targeted issues are pesticide contamination, deteriorating water quality (drinking water as well as groundwater), over-use of plastics, malnutrition, tobacco usage, allergic diseases, groundwater contamination due to exposure to industrial waste (fertilizer industry and pharmaceutical industry), high pesticide usage, poor sanitation facilities, microbial contamination in the water of rivers Ganga and Gomti, food adulteration, maintenance of hygiene etc.
An epidemiological study was conducted to evaluate health risks of employees working in pesticide retail shops in urban areas of Lucknow and Barabanki based on socio-economic status, family history, personal habits and work practices. The study revealed significant decrease of Motor Nerve Conduction Velocity and low Peak Expiratory Flow Rate among shopkeepers. Neurological, ocular, cardiovascular and musculo-skeletal symptoms were also found to be higher among shopkeepers. These findings provide a prima facie evidence of clinical manifestations because of multiple exposures to pesticides and poor safety culture at work place.
Monitoring of pesticide residues in market basket samples of vegetables from Lucknow City was carried out. The study assessed 48 pesticide residues including organochlorines, organophosphates, synthetic pyrethroids, and herbicides in 20 types of vegetables (including leafy, root, modified stem, and fruity vegetables like bitter gourd, jack fruit, French-bean, onion, colocassia, pointed gourd, capsicum, spinach, potato, fenugreek seeds, carrot, radish, cucumber, beetroot, brinjal, cauliflower, cabbage, tomato, okra, and bottle gourd). Twenty-three pesticides were detected of the 48 pesticides analyzed in the samples with the range of 0.005-12.35 mg kg-1. In some vegetables like radish, cucumber, cauliflower, cabbage, and okra, the detected pesticides (I-HCH, Permethrin-II, Dichlorvos, and Chlorofenvinfos) were above maximum residues limit.
In a surveillance study, Curcumin, the principal curcuminoid of turmeric responsible for its yellow color and measure of quality was monitored in loose versus branded turmeric powders. The study shows that curcumin content in branded samples ranged from 2 to 4% while non-branded samples had 0.3 to 2.7%. Almost 17% of loose powders showed presence of extraneous color-metanil yellow, in the range of 1 - 8.6 mg per g. Thus there is a need to prescribe realistic curcumin limits for turmeric powder.
