We have undertaken a systematic review and meta-analysis to investigate the association between maternal exposure to air pollutants and outcomes of in vitro fertilization (IVF). Studies were identified through a comprehensive online search. After standardizing all air pollution concentrations to 10 μg/m, we analyzed the levels of six air pollutants (PM2.5, PM10, O3, NO2, CO, and SO2) by applying a random effects model. A total of five articles met inclusion criteria upon final reviewing. Exposure to PM10, NO2, and CO was linked to the risk of ectopic pregnancy, while exposure to O3 was found to have a reverse association with biochemical pregnancy. Additionally, our analysis indicated a negative association between exposure to PM10, NO2, CO, and SO2 and live birth rates, as well as between NO2 exposure and intrauterine pregnancy. Our study emphasized the relationship between exposure to ambient air pollution and negative effects on pregnancy outcomes for women undergoing IVF.

In this research, nineteen (19) samples were collected and analyzed with the following objectives: to evaluate the activity concentration of radionuclides, assess gamma absorption, determine indoor radon concentration, and evaluate the public health impact of building materials used in Katsina State, Nigeria. The study aimed to provide critical data that would inform safe construction practices and regulatory compliance. Samples were sourced locally from various quarry sites, while materials such as cement, paint, tiles, and ceiling materials were purchased from local markets.

Evaluation of industrial air pollution contribution by type of industry in Pasir Gudang using AERMOD.

Environ Monit Assess

March 2025

Faculty of Chemical and Energy Engineering, Faculty of Engineering, Universiti Teknologi Malaysia, Skudai, Johor Bahru, Johor, Malaysia.

In industrialized areas, air pollution is a recurring problem, especially in areas with high manufacturing and energy-intensive businesses. The challenge lies in the tension between industrial growth and environmental protection, as these sectors significantly contribute to pollution, resource depletion, and climate change. The objectives of the study were (1) to assess the contribution of each industrial group to the air quality in and around the Pasir Gudang industrial area, Malaysia, and (2) to evaluate the Air Pollution Index (API).

Purpose: Nutri-Score aims to aid consumers in making informed food choices based on nutritional quality. To guide consumers regarding both the nutritional quality and environmental impact of foods, it would be beneficial when Nutri-Score could also discriminate foods by environmental impact. This study investigated the association of Nutri-Score with the environmental impact indicators greenhouse gas (GHG) emissions and blue water consumption.

Raman-Polarization-Fluorescence Spectroscopic Lidar for Real-Time Detection of Humic-like Substance Profiles.

Environ Sci Technol

March 2025

Key Laboratory for Semi-Arid Climate Change of the Ministry of Education, College of Atmospheric Sciences, Lanzhou University, Lanzhou 730000, China.

Humic-like substances (HULIS) widely exist in the atmosphere and may strongly affect human health, environment, and climate. However, there are still no accurate methods for detecting the vertical distribution of HULIS. Here, a Raman-Polarization-Fluorescence Spectroscopic Lidar (RPFSL) was developed to simultaneously measure 64-channel broad fluorescence spectra (370-710 nm) of atmospheric aerosols at an excitation wavelength of 355 nm.

Persulfate-based advanced oxidation processes (PS-AOPs) catalyzed by carbon-based catalysts are promising for removing organic pollutants via radical/non-radical pathways. However, the activation efficiency of peroxymonosulfate (PMS) or peroxydisulfate (PDS) usage and the reaction mechanism remain insufficiently understood. In this study, the effects of PMS/PDS dosage on the degradation of bisphenol A (BPA, 10 mg/L) were evaluated using N-doped biochar (N-BC, 0.
