Heavy metals released from industries causes severe environmental pollution in developing countries. This study has been conducted to evaluate the intensity of heavy metals pollution in soil at 0, 30 and 60 m distances from waste carrying canal of Bhaluka industrial area of Mymensingh, Bangladesh. Lead (Pb), chromium (Cr), copper (Cu), zinc (Zn), iron (Fe) and manganese (Mn) concentrations in soils decreased gradually with the increase of distance from waste canal. Maximum concentration was found at 60 to 0 m distance varied from 67.
The pandemic COVID-19 has slowed down human activities globally and throwing countries into a slump and possibly economic depression. Bangladesh, a growing economic country, is also experiencing severe economic shockwaves. Besides the economic shock, it is also facing an imbalance in the food supply in all of its channels. The purpose of this paper is to provide a general understanding of the possible impacts of COVID-19 on food supply in Bangladesh. The paper presents a brief summary of the global COVID-19 situation and the current food supply status concerning COVID-19. In Bangladesh, the trend of COVID-19 cases is increasing and due to the lockdown situation, the food supply is hampering badly. Since most farmers are not adapted to mechanized agriculture and facing labour shortages, their production has fallen at risk in terms of harvesting. Due to buyer shortage and unavailability of supply channels, products are being forced to sell at a low price and it will take years to overcome this shock as the prognosis of COVID-19 is still unknown to all. Though the government has taken some policy measures to maintain a sufficient food supply, protect the agriculture sector, and mitigate the possible losses.
Abstract:The population increase has not only increased the fresh water demand but also increased the volume of wastewater generated. Treated or recycled wastewater (RWW) appears to be the only water resource that is increasing as other sources are dwindling. Increasing need for water has resulted in the emergence of domestic wastewater application for agriculture and its relative use. The present study was conducted at
