| halfgeleider | semiconductor (A solid crystalline material whose electrical conductivity is intermediate between that of a metal and an insulator and is usually strongly temperature-dependent) | |
| halfmetaal | semi-metal | |
| halfmetaal | semimetal | |
| halfmetaal | semi-metal (An element having some properties characteristic of metals and others of non-metals. Many metalloids give rise to an amphoteric oxide (e.g. arsenic or antimony) and many are semiconductors) | |
| halfnatuurlijke droge grasformaties en vegetaties met struikopslag | semi-natural dry grasslands and scrubland facies | |
| halfsteppe | pre-steppe | |
| halfsteppe met gras en eenjarige planten | pseudo-steppe with grasses and annuals of the Thero-Brachypodietea | |
| halfsteppe struikvegetatie | pre-steppe brush | |
| halfwaardetijd | half-life | |
| haling | seiche | |
| halofiele plant | halophyte | |
| haloform | haloform (A haloalkane, containing three halogen atoms, e.g. iodoform, CHI3; a haloform reaction is a reaction to produce haloforms from a ketone. For example, if propanone is treated with bleaching powder, the chlorinated ketone so formed reacts to form chloroform) | |
| halofyt | halophyte | |
| halogeenbevattende verontreinigende stof | halogenated pollutant | |
| halogeenbevattende verontreinigende stof | halogenated pollutant (An organic compound bonded with one of the five halogen elements (astatine, bromine, chlorine, fluorine, and iodine). Several of these compounds contribute to reductions in the concentration of ozone in the stratosphere) | |
| halogeenbifenyl | halogenated biphenyl (Halogen derivatives of biphenyl) | |
| halogeenbifenyl | halogenated biphenyl | |
| halogeenbifenylen | halogenated biphenyl | |
| halogeenfenol | halogenated phenol (Halogen derivatives of phenol) | |
| halogeenfenol | halogenated phenol |
