Bioaccumulation of Lead (Pb) content in three species bivalves in Jakarta Bay, Indonesia
Environmental pollution by heavy metals has become a serious problem in Jakarta Bay. Mobilization of heavy metals as a result of anthropogenic activities has caused the release of heavy metals into the environment, one of which is Pb. Several methods already used to clean up the environment from these kinds of contaminants, but most of […]
Transformational and transactional leadership practices in community forestry in Cameroon
Transformational leadership style is characterized by the leader that empowers community members, causing positive social change and inducing sustainable development. Whereas in transactional leadership style the leader focuses on using community members as a mean to arrive at his end, with no consideration for their empowerment. This study assessed the leadership practice of community forests […]
Effect of silicon and silicon nanoparticles on lead-treated wheat seedlings in hydroponic condition
The current study was designed to elucidate the effect of silicon and silicon nanoparticles on lead-treated wheat seedlings in hydroponic condition. Pb treatments decreased the shoot length, leaf area, shoot fresh weight, shoot dry weight, roots fresh weight and roots dry weight of wheat seedlings. The photosynthetic pigments (chlorophyll “a”, chlorophyll “b”, carotenoids, and total […]
Effect of lead on the morphology of erythrocytes in red tilapia (Oreochromis sp.)
The study investigated the effect of lead at concentrations of 0.5 mgL-1, 1.0 mgL-1, 1.5 mgL-1 on the morphology of red blood cells in Oreochromis sp. Experimental results showed that at lead concentrations of 0.5 mgL-1, 1.0 mgL-1, 1.5 mgL-1, the size of the major axis of erythrocytes decreases gradually compared to the control, decreased […]
Toxic heavy metal lead (Pb) contamination of soils, plants and waters in Hayat Abad Industrial Estate, Peshawar, Khyber Pakhtunkhwa
The present research studies were carried out in the Hayatabad Industrial Estate Peshawar to analyze the concentration of the Lead (Pb) in the soil and plant parts (Root and Shoots). Metals were analyzed in the soil of the root zone, in root and shoot of each plant. Phytoremediation potential of the analyzed plants grown in […]
Liming leads to high bean and maize yield on a strongly acid tea soil
Acid soils are very common in tea zones. These soils have a pH below 5.0. Below this pH, not only do the soils exhibit toxicity of aluminum and manganese but are deficient of calcium, magnesium, phosphorus and molybdenum, hence becoming chemically infertile. Liming is one cheap way of reclaiming these soils. The staple food crops […]
Contaminations in metallic trace elements (Lead, cadmium) of urban and periurban market garden perimeters in the municipality of Lokossa in Benin
Faced with the challenge of global food security, the production and consumption of vegetables in urban and peri-urban areas are a nutritional asset. However, demographic pressure, poorly regulated cultivation practices and growing pollution cannot guarantee the sanitary quality of the products harvested. This study aims to evaluate the metallic contamination of the soil, irrigation water […]
Urbanization in Lahore leads to Respiratory Issues – A Microbiological Perspective
Pakistan is an important country of South Asia. Lahore is its historical city with rich cultural values. The development of cities like construction of new roads, is indication of economic progress of a country. During last decade, Lahore city remains in the state of construction of new roads for providing Metro bus service facilities to […]
Evaluation of lead and arsenic content of Azardirachta indica seed oil and Citrus sinensis peel oil creams as mosquito repellent
There is an increase preference for plant-based repellents due to their effectiveness, environmentally friendliness and biodegradable nature. It is therefore necessary to ascertain the safety of these repellents by analysing their heavy metal content. This study has shown that lead and arsenic content of Azadirachta indica seed oil cream and Citrus sinensis peel oil cream […]
Hepato-protective capacity of Morus (Morus macroura) fruit extract against Lead treated mice: A histopathological study
Present research work focuses on hepatotoxicity of lead exposure and hepato-regenerative potential of Morus macroura Black (MMB) fruit extract post treatment. 15 male mice were distributed into three groups (n=5) that is, 1: CO group (without any treatment), 2: Pb group (50 ppm lead ion in lead acetate dissolved in drinking water), 3: Pb+MMB group […]
