History

The oldest name of the area is ''Tha Chin'' ('Chinese pier'), probably referring to the fact that it was a trading port where Chinese junks arrived. In 1548 the city Sakhon Buri was established, and was renamed ''Mahachai'' in 1704 after the Khlong Mahachai which was dug then and connected with the Tha Chin River near the town. King Mongkut gave it its current name, but the old name ''Mahachai'' is still sometimes used by locals.
It was established by the Act Establishing Changwat Samut Prakan, Changwat Nonthaburi, Changwat Samut Sakhon, and Changwat Nakhon Nayok, Buddhist Era 2489 (1946), which came into force on 9 May 1946.

Economy and environment

Formerly an agricultural- and fisheries-based province, Samut Sakhon in 2020 has more than 6,000 factories, most of them small, employing fewer than 50 workers, and too small to warrant much attention from Thailand's Pollution Control Department (PCD). Small firms lack the budgets to install the environmental gear that would help protect the environment. As a result, Samut Sakhon is one of the most polluted provinces in the nation.

Soil and water samples from the industrial area of Mueang District were found to be contaminated with high levels of arsenic, lead, cadmium, chromium, zinc, copper, and nickel. High levels of persistent organic pollutants (POPS), byproducts of industrial processes, were present in eggs from free-range chickens. An egg tested by researchers was found to have 84 nanograms per kilogram of dioxins and furans, a level 33 times higher than the safety limit observed by the European Union.

The most polluted air in Thailand in 2018 was found to be in Samut Sakhon province. According to the PCD, the level of PM_2.5 in the provincial atmosphere in 2019 was unusually high, measuring as high as 195 micrograms per cubic metre (μg/m³). During the air pollution "season" of 2018–2019, PM_2.5 levels exceeded the PCD's safe threshold of 50 μg/m³ for 41 days.

Samut Sakhon is a leading sea salt producer. According to a survey in 2011, 12,572 rai of salt pans were managed by 242 families in Samut Sakhon.

The number of factories in 2022 was 6,458 with a workforce of 372,282 people.
