Organic farming has developed very rapidly in recent years and has gained importance in maintaining the dynamic soil nutrient. The present study was aimed to investigate the effect of a modified panchagavyam on the physical and biochemical parameters of Vigna radiata. The results of the study revealed that there was an optimal increase in physical parameters (13% increase in shoot and 22% increase in root length). The biochemical parameters (29% carbohydrate, 71% reducing sugar, 49% free aminoacids, 71 % chlorophyll, 23% carotenoids) were also found to be increased. The enzymic and non enzymic antioxidants (45% phenols, 36% tannins, 23% of flavonoids, 23% steroids, 29% catalase and 23% GST) were also noticed to be remarkably increased when compared with that of control and urea treated plants

Long-term exposure to air lead pollution affects school children behavior and health growth. This study aimed to highlight the expected effect of lead contamination on school children activity and behavior. A total of 161participants, which their ages ranged between 6-17 years old, were randomly selected from different cities of Sudan, in which 122 samples were taken as exposed group and 39 as un-exposed (control). Blood lead concentration was determined by NIOSH method using atomic absorption spectrometer. Biochemical parameters were measured in blood serum using standard methods. Data was collected with the aid of writing a questionnaire and analyzed by using SPSS program. Result revealed that the highest lead levels were found in blood serum of children that their school adjacent to high traffic roads with lead levels enough to affect children activity and behavior. In general, higher lead levels were found to be in male rather than female. The study suggested that children schools should be built far from high traffic roads.

The present study was undertaken to assess the impact of the municipal solid wastes (MSW) landfill sites/open dump sites on the quality of the surrounding groundwater. Eight sampling sites were undertaken for the present studies. Values of pH, electrical conductivity, nitrate, sulphate, chloride and magnesium are within the prescribed limits of BIS: 2012 and WHO:2011. The values of Na+ and K+ are also not high except Panki MSW dumping area where the value of Na+ is high. Nitrite is absent. Values of dissolved oxygen are also good in majority of the sites. Values of total dissolved solids of all the groundwater sampling sites are within the prescribed limit of BIS: 2012. It is observed that impact of MSW landfill sites/open dumping ground is more or less negligible on the surrounding groundwater quality of deep boring and as the distance from the MSW site increases, its impact on the surrounding groundwater quality decreases.

The extreme progress of the human civilization in the recent past has been tracked with the rapid development of new chemical technologies and the vast number of new chemical products in the last decades, but as far as sustainability is concerned, it caused a serious negative impact on the environment that turned the attention of the environmentalists to think of remedial actions for the negative impacts (monitoring environmental pollution, reduction of pollutants, recycling, etc). Essentially, the most effective way to reduce the negative impacts is to design and innovation in the manufacturing processes, taking into account energy, materials, atom economy, and finally the life cycle of the products and their practical recycling into new materials. Green chemistry is the utilization of a set of principles that will help reduce the use and generation of hazardous substances during the manufacture and application of chemical products. Green chemistry aims to protect the environment not by cleaning up, but by inventing new chemical processes that do not pollute. It is a rapidly developing and an important area in the chemical sciences and also going to play the major role in the sustainability of the mankind in the future.

Development of green nanotechnology is making the interest of researchers towards biosynthesis of nanoparticles. In this work, copper oxides nanoparticles were synthesized from the aqueous leaf extract of Musanga cecropioides. The formation of the nanoparticles was proven by ultraviolet-visible spectroscopy analysis. Infrared spectroscopy in the mid-infrared region of the synthesized copper nanoparticles provide evidence of the creation of chemical bonds with molecules of the plant leaf extract. The catalytic activity of copper nanoparticles was demonstrated on textiles colorants such as methylene blue, eosyne Y and methyl orange. The degradation efficacity of the copper nanoparticles is high to moderate, been 92.02%, 53.67% and 33.81% for methylene blue, eosyne Y and methyl orange respectively
