Incessant Risk Alarms Associated with Farming and Consuming Crops Cultivated in Host Communities of Gold Mining Operations in Ghana: Truth, Exaggeration, Ignorance or Mischief

Kenneth Bedu-Addo, Martha Ofori-Kuragu and Kwaku Boaky Apau

Article Type: Original Research | First Published: December 31, 2018

Heavy metals and metalloids, some of which are extremely beneficial for the survival of humans, flora and fauna can have devastating effects on same and the environment. Bioaccumulation and bio-magnification two methods via which metals and metalloids are assimilated into food chains as well as dermal and ingestion exposure to heavy metals and metalloids are believed by many residents in the Obuasi Municipality as leading public health threats to peasant farmers, their spouses and children. Risk...

Exposure and Risk Assessment of Selected Chemical Hazards in Cabbage and Lettuce

Isaac W Ofosu, Samuel Akomea-Frempong, Emmanuel De-Graft J Owusu-Ansah and Godfred Darko

Article Type: Original Research | First Published: November 26, 2018

Many health-conscious consumers are increasingly making deliberate choices for plant-based diets because probably they think they were safer. Majority of these consumers who dwell in cities therefore demand leafy vegetables for their daily consumption. The demand has created the opportunity for many urban dwellers to join the business of vegetable cultivation using every space available. Urbanization is associated with industrialization, and with it comes the attendant anthropogenic hazards. Sub...

A Review of Environmental Contamination by Organochlorine and Organophosphorus Pesticides in Egypt

Farag M Malhat, Naglaa M Loutfy, Sara M Greish and Mohamed Tawfic Ahmed

Article Type: Review Article | First Published: November 26, 2018

All pesticides are potentially toxic to all sorts of life and some are even classified as probable human carcinogens, neutrotoxics and endocrine system disruptors. The toxicity level of a pesticide depends on the lethal dose (LD) of the chemical, the length of exposure, and the route of entry or absorption by the body. There are many different pesticides in use today with very different modes of action and levels of toxicity. To protect the public, WHO has developed a hazard classification syste...

Enhancing the Raman Scattering for Diagnosis and Treatment of Human Cancer Cells, Tissues and Tumors using Cadmium Oxide (Cdo) Nanoparticles

Alireza Heidari

Article Type: Research Article | First Published: September 28, 2018

In the current paper, the Localized Surface Plasmon Resonance (LSPR) effect induced by Cadmium Oxide (CdO) nanoparticles is used to observe Raman spectrum of human cancer cells, tissues and tumors. The diagnosis and treatment of human cancer cells, tissues and tumors in sample is investigated through Nanomaterial Surface Energy Transfer (NSET) process from human cancer cells, tissues and tumors to the surface of nanoparticles, and Surface Enhanced Raman Scattering (SERS) process, as effective fa...

Demonstrated Spatial Irrelevance of Gray Fox at Contaminated Sites: Are Ecological Risk Assessments for Mammals Necessary?

Lawrence V Tannenbaum, David M Bullis, Nicholas R Deuel, L Mike Conner, Michael J Chamberlain and Karl V Miller

Article Type: Research Article | First Published: June 30, 2018

Ecological risk assessments (ERAs) for contaminated terrestrial sites regularly include mammals as receptors-of-concern whose home ranges dwarf the sites by tens of times. As a consequence, opportunities to sustain chemical exposures of concern are greatly limited. In having notably miniscule densities as well, wide-ranging mammals are poorly selected species to evaluate because true populations are effectively non-existent at sites. Collectively, the case can be made that wide-ranging mammals a...

Recent Advances in Mercury Detection; Towards Enabling a Sensitive and Rapid Point-of-Check Measurement

Nurfatini Busairi and Amir Syahir

Article Type: Research Article | First Published: April 09, 2018

Heavy metals emission, in particular, mercury is ever increasing due to global urbanization and industrialization. Due to increasing number of health problems related to heavy metals contamination, monitoring it becomes a crucial task for authorities and environmentalists. Therefore, the development of a nanobiosensing technique that can detect mercury ions as low as 1 ppb for its limit of quantification is necessary to provide sufficient information to ensure a sustainable and healthy environme...

Evaluation of In Vitro Cytotoxicity of Zinc Oxide (Zno) Nanoparticles Using Human Cell Lines

A Rama Narsimha Reddy and L Srividya

Article Type: Research Article | First Published: March 16, 2018

The aim of the present study was to evaluate the in vitro toxicity of Zinc Oxide (ZnO) nanoparticles against human alveolar epithelial (A549) cells and human embryonic kidney cells (HEK cells). The toxic effects of nanoparticles were analyzed after 24 hours of incubation with different cell lines using trypan blue dye exclusion method....
