Dry samples were adhered onto an aluminum plate using a double-sided carbon tape (which also removes accumulated

• hpf [76], the significance of disrupting hatching may not manifest until after 24 hpf. However, one further factor that may affect the findings herein is the fact that the LOELs used to define the modelled categories were assigned based upon mass-based concentrations. The issue of dosimetry, that is

Some of these points have been recently reviewed: ideal photosensitizers [23], challenges in formulating photosensitizers, and choosing the right light dosimetry [24], as well as monitoring the

Indeed, protocols adapting the irradiation are tested based on daylight or continuous [26] low irradiation, or using special devices such as fabrics [27] or catheters. The light sources

If NPs are quantified in numbers, is an agglomerate of NPs considered to be one particle or the number of NPs in the agglomerate [14]? Agglomeration can have direct consequences on

The deposited dose per surface area was estimated by using a dosimetry model (ISDD) to directly compare submerged vs ALI exposure concentrations after 4 and 24 h. Unlike ALI exposures, the two
