“…Different biota may respond differently to metal toxicity due to adaptation to their local environment [Ghosh et al, 2021]. For example, metal concentrations influenced by industrial activities may exhibit more toxic effects than in relatively natural and conservation environments Su et al, 2022;Rozirwan et al, 2022). Sediments were identified as the main reservoir of heavy metal pollutants, which are the main habitat for biota, especially in benthic species groups (molluska, crustaceans, and polychaeta), fish, and shrimp [Pandiyan et al, 2021].…”

Industrial activities in coastal areas can produce pollutant substances that are detrimental to the ecological environment. This study aimed to assess the ecological risks of heavy metal pollution in water, sediments, and polychaeta (Neoleanira tetragona) affected by aquaculture, urban rivers, and ports. Water parameters such as temperature, DO, pH, and salinity were measured in situ at fifteen observation stations. Samples were taken at three locations around the aquaculture area, namely the Barong River, the Musi River Estuary as an urban river area, and Tanjung Api-api port in South Sumatra, Indonesia. Analysis of sediment grain size and substrate types using the method of Shepard's triangle Heavy metal concentrations were measured by graphite furnace atomic absorption spectrometry. Then, the data were analyzed using one-way analysis of variance (ANOVA) and post-hoc Tukey statistical analysis. Ecological risk assessment uses the bioconcentration factor (BCF), index geoaccumulation (Igeo), contamination factor (Cf), and pollution load index (PLI). Based on the results, the concentration of heavy metal Pb in water was not detected until 0.625 mg/L, and Cu was not detected. Furthermore, Pb in sediments was 1.261-11.070 mg/kg, Cu was 0.193-19.300 mg/kg, Pb polychaeta was not detected until 0.0044 mg/kg, and Cu ranged from 0.0003-0.0014 mg/kg. Ecological risk assessment for BCF showed that the level of accumulation of polychaeta (N. tetragona) was categorized as an excluder (BCF < 1). Igeo and Cf indicate uncontaminated pollution levels (Igeo < 0) and low contamination (Cf < 1). Meanwhile, the Pollution Load Index is included in the nonpolluted category (PLI <0). Based on the results, the quality of the ecological environment affected by aquaculture, urban rivers, and ports is still classified as safe for ecological risk assessment; further studies are needed regarding the relationship between pollution levels and the physiological response of biota.

“…Liu [15] established a dust concentration early warning model based on the LSTM neural network to study the diffusion characteristics of dust concentration and the effects of meteorological conditions such as temperature, humidity, and wind speed on dust concentration. Su et al [16] established dust monitoring sites in four mines in Northwest China and studied the diffusion trajectory and concentration distribution of mine dust, with Shenfu, Shajing, and Majiatan having a wider range of pollution, and Binchang having a relatively concentrated range of pollution. It was also pointed out that dust enters the environment through air-suspended particulate matter and surface runoff, posing serious hazards to occupational health and safety.…”

With the depletion of shallow mineral resources, deep shaft mining has become an inevitable trend, but there is a lack of systematic review on the hazards of deep shaft mining ecological environment on miners' occupational health. The aim of this paper is to study the impact and main hazards of deep shaft mining ecological environment on miners' occupational health, summarize the existing research results and reveal their limitations, and put forward the latest targeted improvement technologies. The conclusions show that the environmental characteristics of deep mine dust, noise, and high temperature seriously jeopardize occupational health. Pneumoconiosis has become one of the biggest threats, with nearly 14,000 new cases per year since 2009; harmful noise exposure is widespread in deep mines, directly jeopardizing occupational health, with a detection rate of 29.96% of hearing impairment among China's 480,200,000 miners; and the average ground temperatures at the current mining depths of -1,000 m and -2,000 m are 41.84ºC and 69.62ºC, respectively, which are very likely to trigger a variety of heat-related diseases in miners. Miners with a variety of heat-related illnesses. The hazards of these environmental features are seriously underestimated.

“…Many of the substances released into the atmosphere are highly reactive and can form secondary pollutants. Primary and secondary particles released into the atmosphere are then transported up to thousands of kilometres from their sources [5]. During atmospheric transport, the particles may be subjected to various chemical and physical processes that change their shape, size, and composition, and are ultimately deposited on the ground.…”

Air filtration is an urgent global need because, in many countries and regions, the high concentration of inhalable suspended particles in the air is causing irreversible damage to human health. The use of nanofibrous membranes can help to reduce airborne particulate matter because of their large surface area, extremely porous structure, and adjustable pore size. However, despite their unique properties, the main drawbacks of nanofibre membranes are their poor mechanical properties. This review focuses on nanofibrous membranes prepared by electrospinning, a versatile technique in which the process parameters allow control of the morphology and dimensional characteristics of the nanofibres. Recent literature on air filtration is reviewed, focusing on the performance of materials such as pure or mixed polymers, organic–inorganic composites, and ‘green’ materials in the form of nanofibrous membranes. Finally, the recently proposed layered structures for nanofibre-based air filters are reviewed, offering the latest and most innovative solutions.
