Probabilistic human health risk assessment of toxic elements in rice grains from industrially and non-industrially impacted areas of Bangladesh

The concentration of toxic elements (As, Cr, Cu, Fe, Mn, Ni, Pb, Zn) in rice grains varies across industrially and non-industrially impacted agricultural areas. This contamination is particularly critical for countries like Bangladesh, where rice is the staple food. This study assessed the potential health risks and nutritional quality of rice grown in the battery recycling area (BRA), industrial area (IA) and non-industrial area (NIA). Among the toxic elements (TEs) analyzed, As and Pb exceeded the maximum permissible limits (0.20 mg/kg). Pb concentrations were significantly higher in BRA and IA (both 0.32 mg/kg, p < 0.0001) compared to NIA, while As concentration was highest (0.23 mg/kg) in the NIA. The result showed that NIA exhibited a higher non-carcinogenic risk to the exposed population. Conversely, the industrial areas posed comparatively higher carcinogenic risks. The Monte Carlo simulation exhibited the order of total carcinogenic risk (TCR) followed the sequence BRA > IA > NIA. Among the TEs, Ni contributed the most to overall TCR, whereas As posed the highest carcinogenic threat specifically in NIA. Despite contamination concerns, rice grains provided adequate Cu and Fe for dietary intake; however, elevated As and Pb, alongside long-term Ni and Cr risks, require urgent attention.

From revolution to inflation: the economic consequences of the Arab spring on Yemen’s food prices

The Arab Spring began with the hope of restoring democracy but ended in a turmoil. The economic costs of Arab uprisings need to be estimated. This study aims to estimate the economic cost of the Arab uprisings in terms of food inflation. Adopting a case study approach, we focus on Yemen, a country that experienced the Arab uprising starting in January 2011. We define the Arab Spring as the series of events that Yemen experienced after the movements started in January 2011. We employ difference-in-differences (DiD) as an identification strategy to address selection bias. Furthermore, we apply Synthetic DiD and a two-way fixed effects model as robustness checks. We consistently find that the Arab Spring significantly increased food prices in Yemen. This study provides policy implications for relevant stakeholders regarding the impact of political conflicts on food security dynamics.

Ocean Buoy monitoring

Low-cost ocean monitoring systems are increasingly needed to address data gaps in coastal environments, particularly in regions where traditional research infrastructure is limited. This paper presents the design, development, and field deployment of a biophysical ocean buoy (BOB)—a compact, solar-powered autonomous buoy system capable of measuring sea surface temperature, salinity (via electrical conductivity), total dissolved solids, pH, and GPS position. The system features real-time data transmission via the Iridium satellite, local data logging, and modular sensor integration. The BOB was deployed for three missions in the Seto Inland Sea, Japan, ranging from 26–56 h in duration. The system successfully recorded high-resolution environmental data, revealing coastal gradients, diurnal heating cycles, and tidal current reversals. Over 95% of the measurements were successfully recovered, and the Iridium communications exceeded 90% reliability. The temperature and salinity data captured fine-scale variations consistent with freshwater plume interactions and tidal forcing. With a total system cost under USD 2000 and minimal deployment requirements, the BOB offers a scalable solution for distributed ocean monitoring. Its performance suggests strong potential for use in aquaculture monitoring, coastal hazard detection, and climate change research, especially in data-sparse regions. This work contributes to the growing field of democratized ocean observation, combining affordability with operational reliability.
