Vijai Krishna, Vishnu Murari and Sadhana Chaurasia

  • Abstract

     There is an estimation that more than 700 biomedical waste generators are in Patna. These include hospitals, clinics, nursing homes, laboratories, funeral homes, dentists and veterinarians. Patna has several major hospitals. Hundreds of nursing homes and clinics have mushroomed in various residential colonies. Besides these dispensaries, local practitioner’s shops and veterinary hospitals are also there to cure ailing people and animals. These aseptic sanatoriums are visited by thousands of people every day ranging from sick children to accident victims to get cured. It has been observed during the survey of health care centers/facilities that medical institutions generate huge quantities of dangerous and infectious biomedical wastes. Many hospitals just dump their biomedical wastes in the common municipal garbage bin outside the hospital posing grave danger to community residing in surrounding areas in general and rag pickers in particulars, besides considerablyaffecting environment. Study has shown that lack of facilities for disposal of hospital waste and improper use of incinerator in hospitals and nursing homes pose a major environment problem in Patna. Most of the hospitals and nursing homes, surveyed in Patna depend on the municipal corporation to dispose their garbage and have no disposal system of their own. There are total 11 hospitals,1 blood bank and 5 pathological labs are taken under study, these hospitals are of various classes means 4 are of governmental category, 2 are of charitable,1 is military and rest 4 are of private type.

L.M. Shengo, W.N.C. Mutiti, K.A. Nonda and T.A. Mukadi

  • Abstract

    The urban agriculture of cabbages is an additional source of income for the public sector employees. It is also a source of food for the jobless peoples in the developing countries. However, it is often practiced on soils contaminated by heavy metals. That is why it is looked at by the experts involved in the health sector as an issue of great concern. Indeed, the locally grown cabbages can contain heavy metals to high levels brought by the fertilization of the soils with the households' wastes. Heavy metals can build-up in cabbages because their watering is done using water from the rivers that are reputed to experience the pollution from the mineral origin. The present research has been conducted with the aim to assess risks to human health by heavy metals through the intake of cabbages grown at contaminated sites in the city of Likasi located in the Democratic  Republic of Congo (DRC). It is based on the determination of the levels of heavy metals in the agricultural soils and in the locally grown cabbages as well as on the calculation of the hazard indexes of cadmium and lead using the RISC4 Workbench software. Based on the obtained results, it has been concluded that the soils used in the urbanagriculture are highly polluted by heavy metals leading to contamination of the locally grown cabbages.Indeed, the levels of cadmium and lead contained in cabbages surpass the maximal limit recommended for the edible plants. Their intake could endanger the consumers' health through the exposure to the diseases arising due to ingestion of the above-mentioned heavy metals.

Use of Natural Fiber for Fabrication of Fiber Reinforced Epoxy Based Hybrid Composite

Saroj Singh Chahar and A. K. Singh

  • Abstract

    Use of synthetic non degradable materials has been a matter of concern lately. The same concern has been expressed in case of fiber reinforced composites. Scientists have called for the immediate replacement of synthetic fibers by a suitable one. One important development is the use of natural fibers. The use of natural fibres as a replacement for traditional glass fibres in composites has gained increasing importance in recent years as environmental concerns have led to a quest for sustainable alternatives. There are various other advantages. Natural fibers, compared to many synthetic fibers, exhibit better mechanical properties, such as stiffness, impact strength, flexibility and modulus.Nevertheless, natural fibre composites have generally been found to have limitations in their other mechanical properties.In this study, epoxy based composite is prepared with hemp (Cannabis sativa) and glass fiber as reinforcement. Composite was prepared with hand layup technique. Various properties of the fabricated material like tensile strength, flexural strength and hardness were found by testing the material as per ASTM standards to assess the suitability of hemp fibres to replace synthetic fibres.SEM is used to study the nature of fractures while testing.
