To investigate the bioavailability and bio-enrichment of metals from soils to vegetables, the concentrations of ni, Pb, zn, and Cu in vegetables and their grown soils sampled from eight suburban areas of nanjing, china, were determined, and the fractions of these metals in soils was characterized by using the bcr sequential extraction procedure. The results showed that the residual fraction was...

Metals are being utilized of ways in industries and agriculture; particularly heavy metals such as Mercury, Lead, Arsenic and Cadmium constitute a significant potential threat to human health because they are associated to many adverse effects on health. Due to the increasing pollution, concentrations of various chemical compounds have increased in aquatic environments. Water contaminants have ...

The geochemical condition of surface sediments in a tropical estuary and adjoining shelf region is presented for their elemental interactions using statistical methods. Principal component analysis separated two clusters comprising of (i) heavy metals possessing significant correlation with texture (organic carbon, clay and silt), which belong to sediments in the shelf region and (ii) heavy met...

Pit latrines are on-site sanitation systems for accumulation and stabilization of faecal matter, urine and probably some other materials added to the system over a certain period of time. However, the process of anaerobic decomposition of materials in pit latrines is slow, resulting into build up of organic waste, odour production and fly nuisance which could pose significant risks to public he...

The major route of cadmium (Cd) intake by non-smokers is through food ingestion. Cd is a non-essential metal absorbed through one or more transporters of essential metal ions. Expression of these transporters is affected by nutritional status. To investigate the risk factors for Cd toxicity, the effects of deficiency of essential metals on hepatic and renal accumulation of Cd were studied in mi...

Nine-banded armadillos (Dasypus novemcinctus) are widespread and abundant New World mammals with a lifestyle that entails prolonged, intimate contact with soils. Thus, armadillos would seem a promising candidate as a sentinel species to monitor chemical contamination in terrestrial ecosystems. Surprisingly, there have been virtually no toxicology studies on armadillos. Here, we provide the firs...

Concentration of metals (Zn, Cu and Pb) in the edible portion of commercially important blood cockle (Anadara granosa) collected from Langkawi Island, Malaysia was analyzed. Samples were collected from 3 different stations namely Kuah (KU), Kuala Triang (KT) and Pantai Kok (PK) during 2009. Heavy metal concentrations were detected using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) with...

Transition metal ion has been receiving a great attention in the recent years, as the high concentration of toxic metal ions. This paper deals with short review and to study the various types of transition metals present in waste water released from Pulp and Paper effluents. These are being constantly poured into the environment, which result in the long lasting bio-hazards in the aquatic eco-s...

SUMMARY Ionic polymer metal composites (IPMC) have been widely investigated as newly-emerging materials for transducer applications due to their good performance, such as low weight, good flexibility and large strain. A bio-inspired design was described and applied to build 3-D papillae dome structure for vectorial tactile sensors. INTRODUCTION The electrical-chemical-mechanical effect in ionic...

The present research was designed to study and compare the biochemical parameters in Labeo rohita due to exceptional nutritional value of this fish as a protein source in developing countries. The protein and heavy metal (Zn, Cu, Ni) activities were determined spectrophotometrically. The proximate analysis of L. rohita collected from different localities of Pakistan revealed that the protein (1...
