“…The small particles of different plastics with a diameter of less than 5 mm are regarded as microplastics (MPs). They have already largely contaminated water, air, and soil around the globe [106] and the Pakistani environment is no different in being contaminated with MPs [107][108][109][110]. Feeding, on the contaminated water and nectar, and even flying through the contaminated air exposes honey bees to MPs.…”

Biodiversity and Challenges of Honey Bee Population in Pakistan

Honey bees are important pollinators that support food security and nature’s biodiversity. They are also a source of various honey bee-derived products (api-products) used in the food, pharmaceutical, and cosmetic industries. However, various biological, chemical and physical factors threaten the population and biodiversity of feral and managed honey bees. These challenges have not been elaborated upon in the Pakistani context; therefore, this review aims to identify and describe the menaces to feral and domesticated populations of honey bees in Pakistan. Four honey bee species are reported in the country, with the Western honey bee (Apis mellifera) currently being the main domesticated species. Climate change and urbanization are altering the habitats of honey bees. Additionally, agrochemicals are extensively used to manage emerging pests, exacerbating environmental pollution. The air quality in the majority of urban areas is toxic for honey bees. Although remote forest areas can provide habitat and food for these insects, low forest cover and non-sustainable silviculture are still significant hurdles. Microplastics and antimicrobials are impacting the fitness of honey bees and also appear in their products, making it a One-Health issue. Electromagnetic signals also influence honey bee health and behavior. Overall, all these factors influence honey bee health and colony fitness, ultimately causing population declines in both managed and wild honey bees. The purpose of this information is to assist decision-makers, researchers, beekeepers and educators in comprehending the obstacles faced by the honey bee population within the context of Pakistan.

“…Biotic factors consist of the ability of organisms to absorb MPs (Botterell et al, 2019), the ability of organisms to degrade MPs (Zeenat et al, 2021), to the organism's ability to act as a vector of MPs (Santos et al, 2021). Meanwhile, abiotic factors consist of seasonal differences, rainfall, humidity, temperature, and ocean currents (Oliveira et al, 2020;Qaiser et al, 2023). The process of abiotic plastic degradation induces a decrease in the pH of seawater (especially if the plastic is old).…”

This study aimed to analyze Microplastics (MPs) contamination in brown algae and sediments, and their bioaccumulation factors, and estimate the risk to human health associated with exposure to ingested MPs collected from the water of the Sanur Beach, Bali Province. The samples were collected from three beaches which were determined using a purposive sampling method. The mean number of MPs found in P. australis was the same on all beaches, namely 17 items/seaweed, higher than S. aquifolium on all beaches. Line-shaped MPs were dominantly found in all algae (98.76%). A high percentage of line-shaped MPs was found in sediments at Mertasari and Semawang Beaches, but not at Sindhu Beach. The highest mean size of MPs in algae was found in P. australis at Semawang Beach, and sediments at Mertasari beach. The highest concentrations of MPs were also found in P. australis on the three coasts. The BAF value showed that the absorption of MPs in the sediment to brown algae was still low (<1). Values related to intake of brown algae consumption ranged from 190.58-1429.41 MPs item/week adjusted for calculation recommendations.

“…Erosion transports chemical laden water in the river thereby increasing its chemical composition and concentration. This may be detrimental to aquatic organisms [16]. The heat from burning shrinks the mangrove leaves and impacts their photosynthetic capability.…”

Wetland soils derive their chemical composition from the sedimentary rock underneath. Among the metals produced are trace and nutrient elements which facilitate plant growth. Bush burning near mangrove forest is a common practice that has not been given much attention despite its negative impact on the environment. We thus hypothesize that the application of fire on wetland soil will negatively impact the soil chemistry. We collected soil samples from burnt and unburnt soilsat different distances from the point of burning to compare the concentration of nutrient elements (Calcium (Ca 2+ ), iron (Fe), Magnesium (Mg), Nitrate ( 3 NO − ), Phosphate ( 3 4
