In this study we used the vegetables and green leafy vegetables such as cabbage, cucumber, cauliflower, green chilli, coriander, spinach. The accumulation of heavy metal was detected by using Atomic Absorption Spectrophotometry (AAS). The obtained results were showed that the concentration of Cadmium and Chromium were slightly exceeding the recommended maximum acceptable limits. The overall study concludes that the atmospheric deposition, untreated sewage water and poor unhygienic marketing systems were plays a main role in elevating the levels of Cadmium (Cd) and Chromium (Cr) in vegetables and green leafy vegetables.</p> 2021-01-11T00:00:00+01:00 Copyright (c) 2020 Tejaswini M, Guruprasad V, Jessen George, Swati Baliyan Spatio- temporal analysis of pollutants in Karachi coastal water 2020-09-09T15:36:32+02:00 Rabia Majeed Syeda Urooj Fatima Muhammad Azher Khan Moazzam Ali Khan Syed Shahid Shaukat Karachi coast is heavily polluted due to the regular discharge of domestic and industrial effluents. The present study discloses the occurrence and distribution of anthropogenic pollutants in samples collected from ten different places along the coastline of Karachi. The extent of pollution load for three consecutive years was estimated through the GIS technique. The results of the analysis revealed that physical parameters (pH, DO, salinity) were within the permissible limits whereas the level of chemical pollutants (except cyanide, As, Cr, and Cd) were exceptionally higher as compared to National Environmental Quality Standards (NEQS). On average, the study site Creek Avenue showed a higher pollution load of BOD, COD cyanide, TKN, and oil and grease. The average concentration of all heavy metals for three consecutive years (2015-2017) was found to be in an order of As&lt;Cr&lt;Cd&lt;Pb&lt;Ni. The study concluded that Karachi coastal area is overwhelmed with heavy loads of chemical and metallic pollution that requires strict regulations to secure the aquatic ecosystem. 2021-01-11T00:00:00+01:00 Copyright (c) 2021 Rabia Majeed, Syeda Urooj Fatima, Muhammad Azher Khan, Moazzam Ali Khan, Syed Shahid Shaukat Variations of Surface Ozone levels in Urban area of India: a focus on night-time residual concentrations 2020-09-01T13:27:10+02:00 Rohit Sharma Kamna Sachdeva Anu R Sharma <p>This study investigates the existing diurnal as well as night time surface ozone concentration trend over Delhi between 1990 and 2012. Secondary data obtained from the National Data Centre (NDC) of the India Meteorological Department (IMD) was analysed to assess the trend in the surface and night-time ozone concentration. This was further used to forecast the variation in the night-time ozone concentration over the city till 2025. A significantly increasing trend of the night-time ozone concentration was observed between 1990 and 2012 evidenced by a +0.158 value of the Mann Kendall test. Moreover, the forecasting of the variations conducted using the Autoregressive Integrated Moving Average (ARIMA) model revealed that the concentration of night-time ozone is expected to increase between the period of 2013 and 2025 if the current trend continues. This is the first study to conduct a trend analysis of night-time ozone concentration for a duration of three decades in the NCT of Delhi. Considering the negative impacts of elevated levels of ozone on the health status of individuals, agricultural productivity and air quality of the city, the present study highlights that it is imperative to take concentrated actions to curb the release of anthropogenic precursors of surface ozone.</p> 2021-01-11T00:00:00+01:00 Copyright (c) 2021 Rohit Sharma, Kamna Sachdeva, Anu R Sharma Biofortification: way forward toward micronutrient deficiency 2020-10-12T09:09:26+02:00 Zain Mushtaq Anum Nazir <p>Half of the World’s people are being affected by micronutrient-deficiencies. Mostly in developing countries, the human development, along with economic development are hindered by malnutrition. The World Health Organization (WHO) have made fighting micronutrient malnutrition, profoundly known as “Hidden Hunger”, the most important priority. The micronutrient deficiency like zinc, iron and vitamin A are the most demolishing among the World’s poor. The organization have focused on food fortification and supplementation to deal with micronutrient.</p> <p>Biofortification is a novel approach in this regard to provide nutrient enrich food staples. WHO emphasize on biofortification through the Harvest Plus-challenge-program to improve micronutrient of the food staple through biotechnological and breeding approaches. Biofortification is cost-effective approach for delivering of micronutrient enrich food crops to poor people, where people cannot afford to use supplementation.</p> <p>Biofortified crops can be a good source of nutrition to the poor people of developing countries.</p> <p>Here, in this review we discussed the biofortification, its discovery leading to development, benefits and prospects towards the development of biofortified food-crops.</p> 2021-02-04T00:00:00+01:00 Copyright (c) 2021 Zain Mushtaq, Anum Nazir Measurement of radon and heavy metal concentrations in groundwater around Ota, Ogun State, Nigeria. 2020-12-14T15:13:34+01:00 Pauline Jidele Oluwaseun Dosunmu Kayode Ajayi Augustine Ademola <p>This study investigated the concentrations of radon and some heavy metals in drinking water in Ota; an industrial hub of south-western Nigeria. RAD-7; an active electronic device produced by the Durridge Company in the USA was used for measurement of radon concentration and Atomic Absorption Spectrometer for heavy metals. Twenty (20) water samples were collected for this study. Radon concentration in the samples varied from 2.3 to 34.5 Bq L<sup>-1</sup>, with a mean of 7.7 Bq L<sup>-1</sup>. The committed annual effective doses due to the ingestion of radon varied from 0.017 to 0.252 mSv y<sup>-1</sup> with a mean of 0.056 mSv y<sup>-1</sup>. It was observed that 15% of the samples have radon concentration above the 11.1 BqL<sup>-1</sup>; the action level recommended by the United States Environmental Protection Agency. The mean concentration of heavy metals in the water samples were 0.02, 0.014, 0.048, 0.010 and 0.003 mgL<sup>-1</sup>for Cd, Pb, Se, Cr and As, respectively. The concentrations of Pb, Se and As were higher than the WHO permissible limit. This study revealed high concentration of some heavy metals in water in the study areas which may have some delirious effects on the consumers.</p> 2021-02-04T00:00:00+01:00 Copyright (c) 2021 Mrs Jidele Pauline, Mr Dosunmu Oluwaseun, Mr Ajayi Kayode, Dr Ademola Augustine Kolapo
