“…It can be seen that the spectrograms of PSP and DPSP are identical in peak positions. The bands located at 712, 872, and 1426 cm −1 are ascribed to the in‐plane bending vibration, out‐of‐plane bending vibration, and asymmetric stretch of CO 3, respectively. In accordance with a previous study, the organic component in PSP is verified from the peak at around 3428 cm −1 that could be attributed to the OH and NH stretching .…”

“…In recent years, bio‐calcium carbonate has received a growing attention for its distinct superiority over mine calcium carbonate. With the increasing consumption of CaCO 3 , the excessive exploitation of limestone mine has caused a non‐neglectable impact on the geological and ecological environment . In contrast, bio‐CaCO 3 is widely distributed in mollusk shells, crab cuticles, and eggshells as a kind of abundant biomineral, whose resource utilization is inadequate nowadays.…”

Dye‐loaded shell powder (DPSP), as a novel filler and pigment, was fabricated from pearl shell powder (PSP) and Direct Red 28. PSP (mean diameter of 1.94 μm) and DPSP (mean diameter of 1.62 μm) were individually incorporated into polypropylene (PP), and the mechanical, crystallization, and color properties of PSP/PP and DPSP/PP composites were investigated. As compared to PSP, DPSP exhibited superior reinforcing and toughening effects on PP, due to the ameliorated filler–polymer interfacial interaction. The optimal additive amount of DPSP was determined as 10 wt %, under which the tensile strength of PP was raised from 33.17 to 35.37 MPa, flexural strength from 41.16 to 44.35 MPa, and impact strength from 3.77 to 5.98 kJ/m2. In comparison with PSP/PP, higher content of β‐PP phase was confirmed in DPSP/PP composites. Furthermore, uniform redness distribution was achieved in DPSP/PP specimens, demonstrating the good coloration performance of DPSP. The results indicated that DPSP can be utilized for coloration and filling modification of polymers. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47455

“…Our inference is that the best way to accomplish a reliable and effective study is follow a combination of various methodologies of quantitative and qualitative research. We therefore conclude that, the most appropriate methods in our study are a mixture of qualitative, quantitative research, longitudinal and cross-sectional research and classification research [1,5,8,11,13,21,23,29,32,33,42,48,52,53,76,79,91,92,95,98,106,113,124,126,129,136,140,142].…”

The overall aim of this research is the prevention of environmental risk and impact, through the establishment of a present-day environmental observatory centre, equipped with an intelligent monitoring, management and evaluating system. Detecting the environmental pollutants in a timely manner (forecasting), potentially related to adverse health effects while their frequency appears to have increased, shall contribute crucially to avoiding or reducing further inhabitants' exposure to pollutants in high environmental charging areas. A plurality of data will be collected and analyzed in the pilot Observatory. All these data will be gathered by measuring various environmental parameters (physicochemical, microbiological, ionized and not ionized radiation, dust, noise), a number of which will be transmitted wireless from small scale monitoring stations. The data base (territorial distribution of samples, number and frequency of sampling, analyze results, toxicity and risk indicators of environmental pollutants), will be enriched daily/weekly, with satellite data, meteorological data and satellite photographs (image analysis). With the collection, processing and analysis of measured values for various kinds of pollutants from environmental overloaded surfaces, useful conclusions are drawn regarding to the "pollution tendency" in every different area and the possible effects on human in combination with geography and geomorphology. With the use of artificial intelligence (AI) in human body simulators (whole body phantom models) we intend to make a more accurate qualitative and quantitative forecast: worst-best scenario, about as the life quality for residents-who may be exposed to the pollutants-as the direct or indirect medium to long-term adverse effects.

“…Dust is composed of small, dry and solid particles released into the atmosphere by natural or anthropogenic activities and it settles slowly from the atmosphere. Anthropogenic dust is the major contributor of the total dust in the atmosphere (up to 50%) (Csavina et al 2012, Peng et al 2016. As observed by Langmann (2013) and Papagiannis et al (2014) dust emissions are complex and are dependent on meteorological conditions (wind friction velocity and precipitation) and properties (particle size distribution of surface soils, surface roughness length, and soil moisture content).…”

Assessment of heavy metals and radionuclides in dust fallout in the West Rand mining area of South Africa

Windblown dust can contain radioactive materials from mining. These radionuclides when inhaled in dust produce ionizing radiation which damages the cells and tissues in the body. The aim of this study was to assess dust fallout radionuclides in the West Rand mining area of South Africa. Dust fallout monitoring was done using the method (ASTM) D-1739 of 1998 employing multi-directional buckets. Results show that all 9 locations investigated in the different seasons recorded dust fallout rates within stipulated residential limit according to the National Dust Control Regulations (NDCR) (Government Gazette 36974, 1 Nov 2013). Locations 3 in spring (301.93 mg/ m 2 /day) and 6 in winter (589.8 mg/m 2 /day) recorded dust fallout rates with values above the target value of 300 mg/m 2 /day according to guidelines by South African Standards (SANS 1929:2011). The ANOVA tests (p-value < 0.05) indicate that the mean dust fallout rate is significantly different across the seasons, mean dust fallout rate in summer is significantly (p-value < 0.05) more than the autumn by 103.15 mg/m 2 /day. Moderate, positive correlations (0.4 ≤ r < 0.7) exist between average dust fallout rate and wind speed. A weak, negative correlation exist between average dust fallout rate and rainfall with a value of-0.393. All the investigated elements had Enrichment Factor (EF) greater than 1. Cadmium (Cd) and lead (Pb) were extremely enriched (68.36 and 43.48, respectively), whereas Thorium (Th) (7.26) and Chromium (Cr) (9.79) had significant enrichment. Activity concentrations obtained for 226
