Does environmental policy stringency improve nature's health in BRICS economies? Implications for sustainable development.

In our groundbreaking exploration, we meticulously delve into the relationship between environmental policy stringency, international trade dynamics, and financial openness within the BRICS group (Brazil, Russia, India, China, and South Africa) spanning from 1996 to 2021. With a focus on critical variables such as economic growth and technological innovation, our empirical findings challenge conventional wisdom. Surprisingly, we found that those stringent environmental policies, when standing alone, do not invariably lead to reduce CO emissions.

Assessment of medical waste generation rate in Viet Nam.

This study was conducted to estimate medical wastes generation rates in Viet Nam. Within 3 years (from 2017 to 2019), total medical wastes generated daily of 1,737 health-care facilities at different levels from 19/63 provinces in Viet Nam were surveyed. The calculation was based on the median daily generation (in kg) of 6 medical waste groups and total actual patient beds in 9 health-care facility categories.

The historic oil price fluctuation during the Covid-19 pandemic: What are the causes?

On 20 April 2020, the West Texas Intermediate (WTI) crude oil price dropped to negative levels for the first time in history. This study examines the factors underlying the historic oil price fluctuation during the Covid-19 pandemic. The autoregressive distributed lag (ARDL) bounds testing approach incorporating a structural break is applied to the daily series from 17 January to 14 September 2020 to analyze long-run relationships and short-run dynamics.

COVID-19 test-kit trade and trade policy: Implications for developing countries.

At the centre of the multi-dimensional impact of the COVID-19 pandemic, the shortage of medical supplies in countries with weaker healthcare systems significantly reduced the effectiveness of national and international public health interventions. Using a database of test-kit trade flows and barriers, we estimate the price responsiveness of test-kit demand in a global sample of countries. These estimates allow us to investigate the degree to which import tariffs by leading producers could result in a disruption in global supply chains, price increases, and welfare loss.

The energy-growth nexus revisited: An analysis of different types of energy.

This study revisits the nexus between energy consumption and economic growth by considering several energy use types (i.e., total energy, fossil fuel energy, and renewable energy).

Vietnam: country report on children's environmental health.

As a developing country, Vietnam is facing many problems such as environmental pollution caused by industrialization, urbanization and the ethnic minority gap. Besides, Vietnam is one of the 10 countries most vulnerable to the effects of climate change and natural disasters. Vietnam has more than 26.

Food safety aspects of toxic element accumulation in fish from wastewater-fed ponds in Hanoi, Vietnam.

Objective: To evaluate the food safety of fish from production systems in Hanoi feed with domestic and industrial wastewater with respect to the potentially toxic elements such as arsenic (As), cadmium (Cd) and lead (Pb).

Methods: Common carp (Cyprinus carpio), silver carp (Hypophthalmichthys molitrix) and tilapia (Oreochromis niloticus) were sampled from wastewater-fed ponds, and total concentrations of As, Cd and Pb were determined in skin, liver and muscle.

Results: Arsenic, Cd and Pd concentrations were generally low and for many samples below the detection limit.
