Although a large amount of researches have been conducted on these novel nanomaterials, limited comprehensive reviews are published on their biomedical applications and potential environmental and human health effects. The present research aimed at addressing this knowledge gap by examining and discussing:(1) the history, synthesis,structural properties and recent developments of GBNs for biomedical applications;(2) GBNs uses as therapeutics,drug/gene delivery and antibacterial materials;(3) GBNs applications in tissue engineering and in research as biosensors and bioimaging materials; and(4) GBNs potential environmental effects and human health risks. It also discussed the perspectives and challenges associated with the biomedical applications of GBNs.展开更多

However, it remains one of the potential sources of environmental contamination and public health problems. This study examines the health and environmental risks associated with the use of phytosanitary products in market gardening in the town of Abengourou in Cote d’Ivoire. Field surveys carried out among all (30) market gardener sites housed 150 farmers showed that when the products were spread, no health and safety measures were observed. Approximately 80% of the respondents did not wear gloves or face masks. Some products used were not approved for market gardening. Farmers had itching, dizziness, headaches, colds and vomiting on a regular basis when applying the products. The study also revealed the presence of empty packaging in the surrounding surface water and on the ground. In addition to producers, this type of uncontrolled market gardening likely exposes consumers to high health risks and also contributes to environmental degradation. Raising awareness among stakeholders of good agricultural practices could help promote sustainable market gardening. However, studies of the effects of products in such an environment on the health of consumers deserve to be carried out.展开更多
