Today, plastics have been used in many areas and their use have been increasing day by day. This increase in the use of plastic causes environmental pollution as well as negatively affects organisms in the environment and therefore human health. Plastics reach to the water environment through different transport routes. Microplastics that have reached to the water environment are consumed by aquatic organisms. Microplastics in aquatic species (fish, mussels, shrimp, seals, etc.) were highlighted in many studies. Microplastics consumed by aquatic organisms are included in the food network, reaching as far as human consumption. Therefore, the importance of the subject have been emphasized, the evaluation of the studies on microplastics and the risks it poses have been examined in this compilation study which was carried out in order to raise awareness about this issue and to ensure that the necessary measures will be taken.

Pulses are the seeds of legumes that are used for human consumption and include peas, beans, lentils, chickpeas, and faba beans. The bioactivity of pulse metabolites, including isoflavones and saponins, has been the subject of considerable research. However, there has been less consideration regarding the effect of cooking on these potentially beneficial phytochemicals. In this study the changes in concentration of isoflavones and saponins in 13 varieties of pulse including field pea, chickpea, and lentil is studied in whole seed, hydrated seed, and cooked seed. It was found that the concentration of isoflavones studied (genistein, daidzein, formononetin, and biochanin A) was highest in chickpeas, that soaking altered the amount of isoflavones, and that cooking eliminated these isoflavones. By contrast the saponin content of the pulses was more varied and less effect of cooking was observed. This has implications for any dietary recommendation for these pulse varieties with respect to these micro-nutrients.

Abstract Purpose Fermented soybean foods (FSF) is popularly consumed in the South-East Asian countries. Bacillus species, a predominant microorganism present in these foods, have demonstrated beneficial and deleterious impacts on human health. These microorganisms produce bioactive compounds during fermentation that have beneficial impacts in improving human health. However, the health risks associated with FSF, food pathogens, biogenic amines (BAs) production, and late-onset anaphylaxis, remain a concern. The purpose of this review is to present an in-depth analysis of positive and negative impacts as a result of consumption of FSF along with the measures to alleviate health risks for human consumption. Methods This review was composed by scrutinizing contemporary literature of peer-reviewed publications related to Bacillus and FSF. Based on the results from academic journals, this review paper was categorized into FSF, role of Bacillus species in these foods, process of fermentation, beneficial, and adverse influence of these foods along with methods to improve food safety. Special emphasis was given to the potential benefits of bioactive compounds released during fermentation of soybean by Bacillus species. Results The nutritional and functional properties of FSF are well-appreciated, due to the release of peptides and mucilage, which have shown health benefits: in managing cardiac disease, gastric disease, cancer, allergies, hepatic disease, obesity, immune disorders, and especially microbial infections due to the presence of probiotic property, which is a potential alternative to antibiotics. Efficient interventions were established to mitigate pitfalls like the techniques to reduce BAs and food pathogens and by using a defined starter culture to improve the safety and quality of these foods. Conclusion Despite some of the detrimental effects produced by these foods, potential health benefits have been observed. Therefore, soybean foods fermented by Bacillus can be a promising food by integrating effective measures for maintaining safety and quality for human consumption. Further, in vivo analysis on the activity and dietary interventions of bioactive compounds among animal models and human volunteers are yet to be achieved which is essential to commercialize them for safe consumption by humans, especially immunocompromised patients.

Developing countries like Nigeria are faced with increased in generation of domestic, industrial and agricultural wastes, with a large percentage moving. This study evaluates the physico-chemical and some heavy metals concentration in three common species of fish from Tungan Kawo reservoir Kontagora, Nigeria; using standard methods between (July 2018 – February 2019); at four different sampling stations of human activities on the water. Five heavy metals were evaluated (Lead, Copper, Manganese, Iron and Chromium) in the fish samples. Phosphate (0.4 – 2.5) mg/L, Nitrate (3.2 – 7.5) mg/L, Temperature (27 – 32.4) 0C, Dissolved Oxygen (2.4 – 5.2 mg/L), Conductivity (81 – 125 µS/cm), Biochemical Oxygen Demand (1.9 – 4.4 mg/L), Alkalinity (mg/L) and Total Dissolved Solids (117 – 198) ppm were within the standard for drinking water and survival of fish.  However, the pH (6.3 – 9.8) was above the standard for NIS and WHO drinking water but can support aquatic life. Iron (0.64 ± 0.072 mg/kg) was the most highly concentrated in Synodontis clarias while lead (0.01 ± 0.013 mg/kg) was the lowest in Oreochromis niloticus and Coptidon zillii (formerly Tilapia zillii. This current finding indicates that the water is safe for both aquatic life and domestic purpose but not suitable for direct human consumption without being properly treated. However, there is the need for regular monitoring of the heavy metals load in this water body and the aquatic organisms because of the long term effects

<p>A Lake Multi-biotic Integrity Index (LMII) for the China’s second largest interior lake (Dongting Lake) was developed to assess the water quality status using algal and macroinvertebrate metrics. Algae and benthic macroinvertebrate assemblages were sampled at 10 sections across 3 subregions of Dongting Lake. We used a stepwise process to evaluate properties of candidate metrics and selected ten for the LMII: Pampean diatom index, diatom quotient, trophic diatom index, relative abundance diatoms, Margalef index of algae, percent sensitive diatoms, % facultative individuals, % Chironomidae individuals, % predators individuals, and total number of macroinvertebrate taxa. We then tested the accuracy and feasibility of the LMII by comparing the correlation with physical-chemical parameters. Evaluation of the LMII showed that it discriminated well between reference and impaired sections and was strongly related to the major chemical and physical stressors (r = 0.766, P&lt;0.001). The re-scored results from the 10 sections showed that the water quality of western Dongting Lake was good, while that of southern Dongting Lake was relatively good and whereas that of eastern Dongting Lake was poor. The discriminatory biocriteria of the LMII are suitable for the assessment of the water quality of Dongting Lake. Additionally, more metrics belonging to habitat, hydrology, physics and chemistry should be considered into the LMII, so as to establish comprehensive assessment system which can reflect the community structure of aquatic organisms, physical and chemical characteristics of water environment, human activities, and so on.</p>

As these days there is a lot of effect because of environmental pollution and other factors like work pressure human health problems are increasing to a maximum extent. Technology takes a major role in monitoring the health of a individual. This helps to have a copy of recorded values and this helps in taking immediate steps to cure the condition or a precautions needed. As it important to monitor some parameters of the patient we use some sensors. The bluetooth module helps in collecting data from the sensors and sends it to the mobile through Bluetooth and this data can be uploaded to the cloud using Mobile data. This gives perfect data for the doctors to take a decision and give a suggestion to the patient.
