To assess impact of lead poisoning on school academic performance in children.One hundred thirty children of both genders were enrolled. 5 ml of venous blood was collected and the level of blood lead was determined using atomic absorption spectrometry and micro sample flame atomization.
The insufficiency of primary lead sources to satisfy the demand makes the recycling of used batteries necessary. This study quantitatively assesses the impact of different policy instruments on reducing lead pollution from lead-acid battery (LAB) recycling. We develop a system dynamics model to analyze the dynamics of LAB recy- cling considering remanufactures and recyclers spanning formal and informal sectors in the Indian context.
Cattle grazing nearby coal-fired power stations are exposed to fly ash. The present investigation aims to assess the environmental and health impacts of fly ash containing mercury emitted from thermal power plant.
Childhood lead exposure remains a key health concern for officials worldwide, contributing some 600,000 new cases of intellectually disabled children annually. Most children affected by high exposure to lead live in low- and middle-income countries. The leaded gasoline phase out in India was completed in 2000. Yet, in 2020, an estimated 275 million children aged 0 to 9 years had blood lead levels (BLLs) ≥ 5 μg/dL known to adversely affect intelligence and behavior.
A Common Indian cat fish, Clarias batrachus Linneaus was treated with Lead Acetate for sub-acute and chronic exposure to the xenobiotic. The sub acute study included 3 days and 7 days exposure to different concentrations of lead acetate, while chronic study included exposure to 15 ppm lead acetate for 105 days.
Lead (Pb) is a metal of toxicological importance since ancient times and is recognized as a major environmental health risk throughout the world. Lead intoxication is the most frequently diagnosed poisoning in livestock.
High concentrations oflead and cadmium are reported for the first time in the groundwaters of Visakhapatnam area,’ attributable to increased human activities and lack of environmental protection. It suggests an urgent need for remedial measures to overcome future health hazards in this area.
We provide an annual bovine lead exposure estimate for India utilizing random forest modeling, PureEarth’s Toxic Sites Identification Program database, and the FAO’s Gridded Livestock dataset. In aggregate, India suffered 3,273 bovine fatalities, $ 21,437,575 of economic damages, and 23.1 km2 of lethally contaminated land across 222 used lead acidattery recycling sites.
The Pb-contamination of the central India is expected due to both geogenic and anthropogenic pollution. The coal burning is assumed as a major anthropogenic inventory for the Pb contamination in the environment.
Lead (Pb) is a heavy metal with wide applications in many fields, because of its broad range of industrial usage. It is also a common occupational and industrial hazard throughout the world. The toxicity of Pb remains a matter of public health concern, and the awareness about its toxic effects at exposure levels has gained a lot of importance over recent years.
Childhood lead exposure remains a key health concern for officials worldwide, contributing some 600,000 new cases of intellectually disabled children annually. Most children affected by high exposure to lead live in low- and middle-income countries. The leaded gasoline phase out in India was completed in 2000.
Lead toxicity is an important environmental disease and its effects on the human body are devastating. There is almost no function in the human body which is not affected by lead toxicity. Though in countries like US and Canada the use of lead has been controlled up to a certain extent, it is still used vehemently in the developing countries.
In remote areas of India, folk medicine by local unregistered practitioners is quite common. Such practitioners use Sindoor or Vermillion, or Kumkum in their medicinal preparations to cure chronic ailments like joint pain, infertility, asthenia, impotence, and immunological disorders.
In recent years, there has been a growing interest in monitoring the heavy metal Lead (Pb) concentration in spices. Spices can improve the taste of food and can also be a source of many bioactive compounds, but, unfortunately, can also be contaminated with potentially dangerous substances like the heavy metal lead (Pb).
Blood Samples Collected from five different villages around a derelict Lead mine area of Sundargarh district of Odisha state, India, were analyzed by AAS for lead contents. The village Bharatpur is nearby to mining site and other villages are of 1km distance from each other in between 5km radius.
Metallic contaminants including, arsenic, cadmium, lead and mercury exist naturally in the earth’s crust and can be found at various levels in the environment, from where they subsequently enter the food chain.
