MIT SRP

The MIT Superfund Research Program was created in 2017 to be responsive to communities who live near Superfund Sites. In particular, the MIT team leverages scientific research, community engagement, and educational experiences to support people who are concerned about hazardous chemicals in their environment.

Carcinogenic contaminants threaten the health of people living in the Mystic River Watershed (near the Olin, Industriplex, and Wells G&H Superfund sites) and members of Native American ...

Abstract: Herein, we present the development and evaluation of a molecularly imprinted polymer (MIP) sensor for the sensitive and selective detection of N-nitrosodimethylamine (NDMA) in aqueous environments. MIP coatings over electrochemically active electrodes enable NDMA detection with a notably low detection limit of 1.16 ppb. Our findings demonstrate that the ...

Agglutination of liquid Janus emulsions creates optical signals that can be detected and quantified. This study reports the detection and quantitation of Interleukin-6 (IL-6) using emulsions functionalized at the water-organic interface with engineered hyperthermophilic affinity proteins (rcSso7d) derived from ...

N-Nitrosamines are contaminants found throughout the environment, including in drinking water, and many nitrosamines are likely potent carcinogens. Correspondingly, there is need for rapid and cost-effective in-field detection methods that can provide timely information about their contamination ...

The comet assay is a versatile assay for detecting DNA damage in eukaryotic cells. The assay can measure the levels of various types of damage, including DNA strand breaks, abasic sites and alkali-sensitive sites. Furthermore, the assay can also be modified to include purified DNA glycosylases so that alkylated and oxidized bases can be detected. The ...

Aquatic eddy covariance (AEC) is an in situ technique for measuring fluxes in marine and freshwater systems based on the covariance of velocity and concentration measurements. Here, development of a fast multiple-channel sensor (FACT) enables the use of AEC for measurement of benthic fluxes of fluorescent dissolved organic material, salt, and heat at three distinct sites in Massachusetts, USA, including the ...

Cu(I) from tetrakis(acetonitrile)copper(I) hexafluorophosphate ([Cu(MeCN)4]PF6) was complexed with five structurally related phosphines containing N-heterocycles. The interactions between the resulting complexes and some N-nitrosamines were studied using X-ray crystallography as well as emission spectroscopy. Upon complexation, three ...
